Headline Vacuum Pump Exhaust filter housings are available in two materials:- Aluminium and Stainless Steel. All housings, other than Model 420, provide a captured outlet for the ducting away of the aerosol-free exhaust if required. The choice between Aluminium and Stainless Steel will depend upon the chemical composition of the exhaust. If the temperature can exceed 120°C, or if corrosive chemicals are present, stainless steel should be used. All housings are rated at 2 bar pressure at their maximum pressure rating.
