Bullard 41P6 Series airline filters

Max. Air Flow Rate:  75 cfm (2120 lpm)
Inlet Connection:  1” NPT (Fem.)

Bullard 41 Series airline filters can be used in conjunction with other compressor safeguards to supply cleaner air to airline respirators. Seven layer filtration media effectively traps water, oil, particulates, odors, and organic vapors so that cleaner air can be delivered to workers or equipment. Carded cotton, felt material, activated charcoal and activated alumina work in sequence for air filtration.

OSHA requires that employers provide their workers with Grade D breathing air. Bullard 41 Series Filters provide 7-stage filtration that can be combined with carbon monoxide (CO) monitoring and other safeguards to help meet this requirement.

They may also be used to supply drier, cleaner air to tools and pneumatic systems to reduce downtime and repair costs.
