Product detailed description

Oil-free Clean Air CLR-1,1-25M dental compressor on a pressure receiverClean Air CLR · oil-free · 25 l

The basic machine for a small surgery. The CLR-1,1-25M compresses completely without oil, delivers 125 l/min at 5 bar and per the manufacturer serves one to two chairs. The receiver holds 25 l and is epoxy-coated inside against corrosion. At 31 kg it is the lightest machine in the range.

When twenty-five litres without a dryer are enough

When the surgery has one chair and you handle moisture another way — with a central dryer downstream or by draining the receiver regularly. The air is oil-free from the start, so no filter is needed downstream to remove oil.

If you have no dryer and do not want to solve it separately, take the 25MD version: the same machine with an adsorption dryer that dries the air to a −40 °C dew point. It is twelve kilos heavier and somewhat deeper.

Equipment and details

What the CLR-1,1-25M does as standard

  • oil-free pump unit — no oil can reach the air
  • single-stage compressor, direct drive without belts, 1400 rpm
  • 25 l pressure vessel with an epoxy coating inside, working pressure 8 bar
  • cyclone water separator; a dryer can be added separately
  • open design — 71 dB(A) at one metre
  • intake 240 l/min, delivery 125 l/min at 5 bar
  • capacity of 1–2 dental chairs per the manufacturer (50 l/min at 5 bar per chair)
  • 1.1 kW motor on four anti-vibration mounts, electric motor 230/50 V/Hz — an ordinary socket
  • DN 7.2 quick coupling, weight 31 kg, dimensions 470 × 430 × 670 mm
  • two-year warranty

Machine detail

The open design leaves the pump, the cooler and the fittings accessible from above. Servicing and checking the drain take minutes, but the machine hides none of its noise.

Where to go if the CLR-1,1-25M does not fit

With a dryer it is the CLR-1,1-25MD, with twice the receiver the CLR-1,1-50M. The quieter canopy version is the CLR-1,1-30MS. The full overview is in the overview of the whole category.

Delivery is the amount of air the machine supplies at 5 bar (FAD per the manufacturer leaflet); intake is the volume drawn in by the pump unit. The noise figure is the sound pressure at one metre from the machine; the sound power level Lwa is in the parameters. The capacity in chairs is calculated on 50 l/min at 5 bar per chair.

Ventilek advises

Without a dryer, expect to drain the receiver. Water in the pipework is a bigger problem for dental air than oil — and this machine does not solve oil simply because it has none.
