Pall’s bleed air filters get STC for CFM56-7 engines

Pall Corporation announced that the next-generation protection for Bleed Air components for CFM International’s CFM56-7 aircraft engines has received a Supplemental Type Certificate (STC) issued by the Federal Aviation Administration. The STC allows operators to install the equipment on their CFM56-7-powered Boeing 737 aircraft.

The PV100 PUREair Bleed Air Filters were developed in collaboration with a major global airline and offer protection for the high pressure shutoff valve (HPSOV), pressure regulating shutoff valve (PRSOV), high stage regulator (HSR), precooler control valve (PCV), and bleed air regulator (BAR) from contamination-induced failures and wear. The valves protected are critical parts of the aircraft cabin pressurisation and anti-icing systems. The PV100 PUREair Bleed Air Filters use Pall’s advanced sintered filtration media to provide optimal protection balanced with longer filter life. Installing the PV100 PUREair Bleed Air Filter Kit in place of existing bleed air lines helps protect against bleed air trip light warnings that drive costly diversions and maintenance.

Pall PUREair products have been used in critical aircraft systems for more than six decades. Born from the invention of porous stainless steel, these products illustrate Pall’s long-term and continued focus on innovation. Pall Aerospace PUREair Bleed Air products are used on a majority of aircraft engines in service today as OEM equipment.
