1 Air Filters Inlet silencers 1. Description Good filtrationis not only highly important in machineswhich take in air like compressors, vacuum pumps and combustion engines, good inletsilencingisalsobecomingincreasinglyvital. The range described belowoffers a wide choice of high performancefiltertypesforthis application. The range includes some typeswith oilwetted insertswhich can be rinsed outfor small compressorsforthe hobbyand manual crafts sector. All ofthe filters are distinguished bytheir good filtering efficiencyand high contamination absorptionproperties. compactdesign easeofhandling fitted with high efficiency filter elements worldwidesales MAHLE Filtersysteme GmbH Bereich Industriefilter Postfach Öhrin gen Telefon(07941 ) 670 Telefax (07941 ) 67429

Air Breather Filter Pi 0101 Pi 0185 1. Features The Pi 0101 through Pi 0126 breather filters have housings made of noncorrosive material.

The disposable, pleated elements can be replaced in a matter of seconds. The Pi 0140 through Pi 0185 breather filters have a housing made of galvanized sheet metal.

9 Air Breather Filter Pi 0101 Pi Features The Pi 0101 through Pi 0126 breather filters have housings made of noncorrosive material. The air intake is located in the upper section, this prevents surface dust to be drawn in from the tank top. The cover is designed to prevent entry of splashwater. The disposable, pleated elements can be replaced in a matter of seconds. The Pi 0140 through Pi 0185 breather filters have a housing made of galvanized sheet metal. The builtin oring provides accurate sealing at the tank connection. With the choice of Mic or SmL elements the CETOP RP 98 H requirements are fullfilled. These specify the same filtration degree for the breather filter as the system filter utilizes. Molelements prevent oil aerosol from emerging the tank. The oil aerosol coagulate, forming drops within the pleated coalescer layer, which are returned to the tank. Filters are fixed by threads, clamps or flanges.. Air breather filter Pi are offering the following features. Corrosion resistant Compact design Equipped with Mic, SmL and Mol elements High dirt holding capacity Versatile mounting option: screwed, clamped or flanged Versatile combination possibilities Wide range of accessories Worldwide distribution

If the liquid level in the tank rises, the ball rises accordingly and closes the tank outlet by means of the valve disc (*2). The valve disc is flexibly loaded to prevent the permissible pressure inside the tank from being exceeded....
