Product detailed description
Silent Line LN · 270 l · 598 l/minThe ceiling of the low assembly. A49B-4-270L1T has a four-kilowatt two-stage pump and delivers 598 l/min at 11 bar — the most of all five machines in an L1 cabinet on a 270 l receiver. The footprint stays 1,522 × 580 mm and the weight 248 kg, so those forty-five extra litres over the three-kilowatt version cost you no space.
Why the strongest machine in the low assembly
The pump turns at 1,400 rpm instead of 1,300, and that is the whole difference against the three-kilowatt version — the same cabinet, the same receiver, the same weight, 45 l/min more. The noise stays at 89 dB Lwa.
If you need still more air or a calmer run, the low cabinet goes no further: the next machines already use the taller L2 cabinet, which is 27 cm higher and 15 cm wider. The open A49B-4 pump runs at 97 dB Lwa in the Pro Line range; here it is 89 dB.
Equipment and details
What A49B-4-270L1T does as standard
- two-stage oil-lubricated A49B pump with an air aftercooler, V-belt drive, 1,400 rpm
- L1 cabinet of sheet-metal panels lined with sound-absorbing foam, each panel removable on its own
- pulley cooling: the spokes are shaped like fan blades and drive air onto the pump cylinders
- horizontal 270 l pressure receiver forming the base of the machine; condensate drained by a ball valve
- 4 kW electric motor, 400/50 V/Hz, three-phase supply, thermal protection, pressure switch
- intake 598 l/min, working pressure 11 bar
- central control panel with main switch, pressure gauge, pressure regulator and hour counter
- weight 248 kg, dimensions 1,522 × 580 × 1,242 mm; noise 89 dB Lwa, 69 dB at 4 m
- two-year warranty, extension to three years available at extra cost
Machine details
Where to go next if A49B-4-270L1T is not the one
Two decibels calmer is B59-4-270L2T in the taller cabinet; more economical is A49B-3-270L1T. The same pump on a five-hundred-litre receiver is A49B-4-500L1T. The full overview is in the overview of the whole category.
Intake is the volume of air the pump draws in. Noise is given as the sound power level Lwa and as the sound pressure at 4 m from the machine. A piston compressor works in cycles, not without a break. All figures are manufacturer data.
Ventilek recommends
The maximum that fits into the low cabinet. When this is not enough, the next step means a bigger footprint and a taller cabinet — not a stronger motor in the same box.
