PX filter: The medium and high pressure filters from BAUER KOMPRESSOREN
Three pressure levels: 100 bar, 250 bar and 420 bar
Filter elements: coalescence filter and activated carbon filter
Removes: Particles and oil
BAUER PX series of medium and high-pressure coalescing and active charcoal filters are designed to remove particulates, oil droplets and aerosols. They are suitable for air, nitrogen, helium, argon and other gases.
Various air/gas quality standards in accordance with ISO 8573 up to class 1 can be produced depending on the filter type and filter combination.
The solid steel filter housings withstand static and dynamic loads.
All the information you need at your fingertips!
Filter housing
PX filter series housings are made from solid steel and designed to withstand static and dynamic loads from inert gases. Solutions for other gases are optionally available.
The filter housings have connections for gas input and output, condensate drain, differential pressure gauge and wall mounting.
The pressure vessels conform to PED/2014/68/EU standard.
Filter elements
Various filter types are available with different filter grades and filter elements.
Depending on the application and the desired air or gas quality, several filters can be connected in series or combined with the P-Filter or SECCANT purification systems.
Purity classes according to ISO 8573-1:2010 up to class 1 are possible for oil removal and particle removal.
Manual condensate drain
Filter condensate is drained manually.
Wall mount
Practical wall mount for the filter unit, including all mounting fixtures.

¹ Element M and F do not remove oil vapour; values therefore only valid for droplets and aerosols.
² Filter element "A" with activated carbon layer: For removing small amounts of oil vapour.
