P filter systems for breathing air quality conforming to DIN EN 12021*

The P-FilterSystem

P-SystemYou need high pressure breathing air? Why does it need purifying? Without purification, air from a piston compressor conforms in no way with the air quality standards required by divers; it is saturated with moisture, contains oil vapours and may taste and smell of impurities.
Therefore, an air processing system is of prime importance.
Without air purification, serious damage to your health and equipment may ensue. Equipment damage includes cylinder corrosion, equipment malfunctions through impurities and iced up, free flowing regulators. Costly repairs and maintenance are some of the consequences. Also hazardous microorganisms may inhabit the cylinder.

The quality of breathing air is largely based on the purification systems and the design of the compressor block. We have 55 years of high pressure experience and know-how - that pays off!

The BAUER P-Filter systems meet and exceed the following international air quality standards:
Germany: DIN EN 12021* and PNEUROP 6611
United Kingdom BS 4275 (fire services), BS 4001, part 1.2 (diving)
France Plongées Profondes Offshore
USA CGA Grade D+E, Navy Standard Federal Spec. Grade A+B
Canada CSA

With the BAUER P-filter system these international standards are met or clearly surpassed.

The Final Separator

is integrated in the VERTICUS units. The oil and water emulsion collects in the bottom of the separator chamber and is drained manually or by means of an automatic condensate drain (optional).

The P-Filter System

The filter system P41 or P61 are part of the standard delivery scope of supply on the VERTICUS models. The filters are carefully selected to match the units' rate of flow and to provide long filter life. Drying agents in the filter cartridge absorbs the residual humidity and water vapours.

Compressed air is treated in three stages:

A - DRYING by adsorption of water vapour particles

B - NEUTRALISATION by adsorption of oil vapour and disturbing odours

C - MICRO FILTERING by binding suspended particles

BAUER's purification cartridges have a filter capacity of 1000 Nm³ (P41) or 1600 Nm³ (P61) at 200 bar (capacity in terms of free air delivery measured at 1 bar absolute, + 20 °C air temperature and + 30 °C final separator temperature).

Standard Scope of Supply

Purchasing BAUER's P-filter system gives you a complete and functional air/gas purification system with:

  • Micro separator
  • Automatic condensate drain (optional)
  • SECURUS monitoring unit (optional)
  • Component-tested safety valve
  • Corrosion resistant non-return valve
  • Filter system with aluminium pressure vessels (TÜV approved)
  • Pressure maintaining valve
  • All system components are given a special surface treatment for long life corrosion resistance.
