Pro Line Extensive and Expert A39B compressors — one pump, two spec levels
Extensive and Expert · V-belt drive · 10 bar · 50 to 270 lThirteen belt-driven ABAC compressors with the same oil-lubricated A39B pump and two levels of spec. The Extensive (BT) is the base spec: an aftercooler, a regulator with two gauges, one front swivel castor with a brake and an open handle. The Expert (BP) adds two front castors with brakes, a closed handle with a rubber grip and an outlet filter. A 2.2 or 3 kW motor, 393 or 486 l/min of displacement, 10 bar, a horizontal 50 to 270 l tank, single- and three-phase versions. Machines for the workshop, the garage and the tradesman, where tools draw air in longer bursts; we service the ABAC brand.
Which Extensive or Expert A39B — spec, motor and tank
Three choices, in this order: how much spec you want on the machine, how much air the pump should deliver and how much of it the tank should hold. The voltage is then decided by the socket in your workshop.
Extensive (BT), or Expert (BP)
Both spec levels have the same pump, aftercooler, pressure switch, regulator with two gauges and DN 7.2 quick coupling. The Extensive stands on one front swivel castor with a brake and has an open handle; the Expert has two front swivel castors with brakes, a closed handle with a rubber grip and an outlet filter, which catches condensate before it reaches the tool. There are six Extensive machines (90 to 270 l) and seven Expert machines (50 to 270 l).
2.2 kW: 393 l/min, or 3 kW: 486 l/min
The A39B pump runs with a 2.2 kW (3 hp) motor at 1,050 rpm and draws in 393 l/min; with a 3 kW (4 hp) motor at 1,300 rpm it draws in 486 l/min — 93 l/min more for a sander or a gun in longer bursts. The 3 kW motor is always three-phase on 400 V and only on the Extensive (90, 200 and 270 l). Noise 95 dB Lwa (75 dB at 4 m) with 2.2 kW, 96 dB Lwa (76 dB at 4 m) with 3 kW.
A 50 to 270 l tank and the socket
The tank does not add displacement, but it gives the pump its pauses: the fifty for the van and site work, the ninety for a smaller workshop, 150 and 200 l for longer work by one person with a gun or a sander, 270 l where several tools take turns. The CM versions have a single-phase motor for an ordinary 230 V socket (Extensive 150CM, 200CM, 270CM; Expert 50CM, 150CM), the CT versions a three-phase 400 V motor.

Extensive (BT), or Expert (BP) — and when to go for the Export, the A29B or the Expert Zero
Under the guard it is always the same A39B pump: the difference between Extensive and Expert lies in how you move the machine about and in what sits on the outlet. The sister ranges: the Export has the same pump on 230 V, the A29B a smaller pump and the Expert Zero its oil-free variant, the A39B0.
Extensive (BT): the base spec at no extra cost
An aftercooler, a pressure switch, a regulator with two gauges, a DN 7.2 quick coupling, an oil sight glass, a ball valve. One swivel castor with a brake at the front, two 200 mm wheels at the rear and, on top, an open tubular handle for pulling the machine across the workshop. Six machines: 2.2 kW for a 230 V socket with 150, 200 and 270 l, 3 kW on 400 V with 90, 200 and 270 l.
Expert (BP): two front castors, a handle and a filter
The same pump and the same aftercooler, plus two front swivel castors with brakes, a closed handle with a rubber grip and an outlet filter with a bowl next to the regulator. Worth it where the machine is moved every day and the air should go to the tool without condensate. Seven machines with 2.2 kW: 50 l both for an ordinary socket and on 400 V, 90 l on 400 V, 150 l in both voltages, 200 and 270 l on 400 V. An Expert with the same tank and motor costs a little more than the Extensive.
When the Export, the A29B or the Expert Zero
If you want the A39B pump just for a 230 V socket with a 50 or 90 l tank, you will find it at a lower price in the Export range — it runs at 950 rpm and draws in 355 l/min. If 255 or 320 l/min is enough, you pay less for the smaller A29B pump. If you need oil-free air for spraying or upholstery, there is the oil-free A39B0 pump in the Expert Zero range. If you want 11 bar and a sander running non-stop, you move up to the two-stage A49B.
V-belts, a moulded guard and an aftercooler — what is inside
Belts and 1,050 or 1,300 rpm
The motor drives the pump through V-belts with a reduction ratio: with 2.2 kW the pump runs at 1,050, with 3 kW at 1,300 revolutions per minute — slower than direct-drive pumps, which turn with the motor. The pistons and valves do fewer cycles per shift; the belt is a part you replace after years without opening up the pump. You check the oil level in the pump through the sight glass without opening anything.
Moulded belt guard
The guard does more than cover the belt: it is shaped so that the pulley drives cooling air over the finned cylinders of the pump. The machine cools itself even during longer work and the compressed air leaves cooler.
Aftercooler on the outlet
The compressed air leaves the pump through the finned tube of the aftercooler, where it cools down before it enters the tank. The moisture drops out as condensate in the tank, not in the hose at the tool, and you drain it through the ball valve under the tank. On the Expert the outlet filter catches the rest.
Tank, switch and outlet
A horizontal 50 to 270 l tank rated at 10 bar. The pressure switch starts and stops the motor according to pressure; the motor has thermal overload protection. On the outlet there is a pressure regulator, two gauges — tank pressure and tool pressure — and a DN 7.2 quick coupling. The AirTube QR code on the tank opens service videos.

Machine details
Where the Extensive and Expert A39B work
Workshop, garage and tyre shop
A ratchet, an impact wrench, a blow gun, tyre inflation, fitting work: the A39BP-2.2-90CT holds 90 l and 393 l/min for one person working with tools in bursts, and with its handle and two front castors you wheel it from lift to lift. For a fixed spot with a 230 V socket there is the A39BT-2.2-150CM.
Spraying, sanding and longer work
A spray gun, protective coatings, a random orbital sander: the A39BT-2.2-200CM or the A39BP-2.2-200CT holds a reserve the tool draws on for longer before the motor cuts in; a filter belongs upstream of the gun — on the Extensive a regulator with a filter at the workstation, on the Expert the outlet filter already on the machine. For two people with tools at once there is the 3 kW with 486 l/min: the A39BT-3-200CT or 270CT.
The tradesman on the job and in the van
Joiner, fitter, plumber: a stapler, a nail gun, blowing off. The Expert A39BP-2.2-50CM runs from an ordinary socket, at 51 kg it is a two-person lift and two front castors with brakes keep it in place; the same fifty on 400 V from the site distribution board is the A39BP-2.2-50CT.
Accessories and service
The DN 7.2 quick coupling is the same standard as on the hoses, guns and tools across our whole range. The Extensive has a regulator without a filter — for a spray gun add a regulator with a filter at the workstation; the Expert has the outlet filter on the machine already. ABAC belongs to the Atlas Copco group and is one of the brands we repair in our own service workshop; parts for the A39B pump are shared with the Export range, which has the same pump.
- pressure regulator with a filter — A filter and regulator at the workstation for a spray gun — a must with the Extensive.
- spray guns — HVLP and LVLP guns; with 393 l/min and a 200 or 270 l tank the machine keeps up with them for longer spraying.
- impact wrenches — An impact wrench in bursts for the garage — with 90 l or more.
- tyre inflators — Tyre inflation from a tank at 10 bar.
- blow guns — Blowing off parts and machines.
- spiral hoses — Hoses with DN 7.2 quick couplings from the machine to the tool.
- A39B compressor pump — Replacement pump for the whole range; our workshop supplies the parts.
- ABAC compressor service — Warranty and post-warranty repairs of ABAC machines in our workshop; belt, filter and oil replacement.
Where next if neither the Extensive nor the Expert A39B is the right fit
The A39B is the bigger single-stage pump in the belt-driven Pro Line range. If you need a smaller pump, two-stage 11 bar pressure, oil-free air, a lower price for the same pump or a direct-drive machine for a socket, ABAC has alternatives. You will find the whole range, with filters by output, tank and voltage, among all compressors.
- compressors with the A29B pump — Extensive and Expert with the smaller A29B pump — 255 or 320 l/min, 1.5 and 2.2 kW motors, 50 to 200 l.
- two-stage A49B compressors — Two stages and 11 bar for impact wrenches and sanders running non-stop.
- the Pro Line Export range — The same A39B pump just on 230 V, 950 rpm and 355 l/min — at a lower price.
- oil-free Expert Zero compressors — The same belt-driven build, but an oil-free A39B0 pump — for paint shops and upholstery.
- Pro Line A-X clearance — The older range with a wire belt guard on clearance, including the three A-X machines from this listing.
- sound-insulated Silent A29B and A39B compressors — The same pump in a sound-insulated cabinet for running next to the workstation.
- the ABAC Line trade range — Lighter direct-drive machines for a 230 V socket — from the suitcase model to the V36 and V30 twin-cylinder machines.
- workshop compressors — Workshop machines across brands with filters by output and tank.
- compressors with a 200 l tank — 200-litre machines across brands.
- compressors with a 270 l tank — The biggest tanks in the range across brands.
- compressors with a 3 kW motor — Three-kilowatt machines across brands.
Ventilek advises
One pump, two spec levels: the Extensive is for those who put the machine in one place, the Expert for those who wheel it about every day. The difference between BT and BP is not in the pump or the aftercooler — both have those. It is in the castors, the handle and the filter on the outlet, in other words in what you notice when you pull the machine across the workshop a hundred times a week, and in whether water drips from your hose. For a fixed spot with a socket I would take the A39BT-2.2-150CM, for the lift on 400 V the A39BP-2.2-90CT, for a paint shop with two people the A39BT-3-270CT with a filter at the workstation. If you want the machine just for a 230 V socket and at a lower price, look at the Export; if less air is enough, at the A29B.
Frequently asked questions
- How do the Extensive (BT) and the Expert (BP) differ?
- The A39B pump, the aftercooler, the pressure switch, the regulator with two gauges and the DN 7.2 quick coupling are the same on both. The Extensive has one front swivel castor with a brake and an open handle. The Expert has two front swivel castors with brakes, a closed handle with a rubber grip and an outlet filter that catches condensate before the tool. The letter T in the code stands for Extensive, P for Expert.
- 2.2 kW, or 3 kW?
- The 2.2 kW (3 hp) motor turns the pump at 1,050 rpm and gives 393 l/min; the 3 kW (4 hp) motor at 1,300 rpm gives 486 l/min. The three-kilowatt machines are three-phase only and only in the Extensive spec with 90, 200 and 270 l — for two people with tools or a gun with a higher air consumption. If 393 l/min is enough, you have both spec levels and both voltages to choose from.
- What do CM and CT mean in the designation?
- CM is a single-phase motor for an ordinary 230 V socket (Extensive 150CM, 200CM, 270CM; Expert 50CM and 150CM), CT a three-phase 400 V motor. Neither displacement nor pressure changes with the voltage; the three-phase motor needs a 400 V socket, the single-phase a short, adequately rated lead so that start-up does not trip the breaker. Single-phase machines from all the brands we stock are grouped together under 230 V compressors.
- Which tank size should I choose?
- The tank does not add displacement, it only extends the time the tool draws air before the motor cuts in. 50 l is enough for a stapler, tyre inflation and blowing off, and the machine fits in the van; 90 l is the workshop standard for a ratchet and an impact wrench in bursts; 150 and 200 l hold a reserve for a spray gun and longer sanding; 270 l where several tools take turns. Parameter categories compare machines of all brands by tank size, for example compressors with a 150 l tank.
- How much air does the A39B pump deliver?
- With a 2.2 kW motor it draws in 393 l/min at 1,050 rpm, with a 3 kW motor 486 l/min at 1,300 rpm; both fill the tank to 10 bar. How much air your tools actually take and how to work it out is explained in our article on choosing a compressor.
- How loud are they?
- The 2.2 kW machines have 95 dB Lwa and 75 dB at 4 m, the 3 kW machines 96 dB Lwa and 76 dB at 4 m. If you need far fewer decibels, ABAC has the same pump in a sound-insulated cabinet in the Silent range. Stand the machine on a level floor and not tucked into a corner, where the noise bounces back.
- Which model has an outlet filter?
- Every Expert (BP) — from the fifty to the 270 l — has a filter with a bowl next to the regulator, which catches condensate and dirt before the air leaves through the quick coupling to the tool. The Extensive (BT) has a regulator without a filter; if you want to spray with it, add a regulator with a filter at the workstation.
- Why does the A39B have V-belts, and what are the moulded guard and the aftercooler for?
- The belts let the pump run slower than the motor — 1,050 or 1,300 rpm; the pistons do fewer cycles per shift and the pump heats up less. The moulded belt guard guides cooling air from the pulley over the finned cylinders; the aftercooler cools the compressed air before it enters the tank, so the condensate stays in the tank. Lighter machines without belts are in the ABAC Line range.
- What is the warranty?
- Two years on the machine, with an optional extension to three years at extra cost when you buy, and ten years on the tank against rusting through. That goes hand in hand with routine maintenance as per the manual: draining the condensate, checking the oil level in the sight glass, changing the oil and cleaning the intake filter.
- Who is the range for?
- The Extensive for workshops, garages and tradesmen, where tools draw air in bursts and the machine mostly stays put. The Expert for those who wheel the machine around the workshop or garage every day and want air without condensate straight from the machine. A piston machine works in cycles and needs pauses; for a sander or an impact wrench running non-stop and for 11 bar choose the two-stage A49B.
- How does the A39B differ from the A29B, from the Export range and from the Expert Zero?
- The A29B is the smaller pump of the same range — 255 or 320 l/min with 1.5 and 2.2 kW motors, tanks up to 200 l and a lower price. The Export has the same A39B pump, but only with 2.2 kW on 230 V, a 50 or 90 l tank and at 950 rpm — it draws in 355 l/min and costs less. The Expert Zero has the oil-free A39B0 pump for spraying and upholstery. An overview of all the ranges is in the ABAC PRO Line guide.
- Where do I find the service videos, and who does the servicing?
- On the tank there is an AirTube sticker with a QR code — scanned with a phone, it opens instructional and service videos for the pump. Service, belts, filters and oil are handled by our workshop; the other ranges, from the suitcase models to the screw compressors, are in the ABAC brand guide.
All values apply to a 50 Hz supply. Air intake is the amount of air the pump draws in; how much of it reaches the tool depends on the pressure and the tank. Noise is given as the sound power level Lwa and the sound pressure at 4 m from the machine. A piston compressor works in cycles (topping up the tank and pausing), not continuously.
