Product detailed description

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

A complete solution for one chair. The CLR-1,1-25MD adds an adsorption dryer with silica gel to the oil-free pump, so the air enters the receiver at a −40 °C dew point — no water condenses in the pipework or the instruments. Output 125 l/min at 5 bar, receiver 25 l, weight 43 kg.

What the dryer adds

An oil-free machine gives air without oil, but not without moisture. The dryer removes it in two steps: a cyclone separator catches the droplets from the cooler and the silica gel in the tower absorbs the rest. Regeneration happens automatically after every cycle, so it is not replaced like a filter element.

The dryer costs twelve kilos of weight and five centimetres of width against the version without it. Noise and output stay the same — 71 dB(A) at one metre and 125 l/min, exactly as on the 25M.

Equipment and details

What the CLR-1,1-25MD 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
  • adsorption dryer with silica gel — −40 °C dew point, automatic regeneration after every cycle
  • 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 43 kg, dimensions 530 × 470 × 670 mm
  • two-year warranty

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

Without a dryer it is the CLR-1,1-25M, with a fifty-litre receiver the CLR-1,1-50MD. The quietest version with a dryer is the CLR-1,1-30MDS. 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

A −40 °C dew point is well below what a refrigerant dryer reaches. For dentistry it is the right choice — and because the silica gel regenerates itself, there is no consumable to buy.
