LPTA Series Inlet Traps are large-scale particle traps that are rugged, and intended for use in industrial environments. LPTA Series Traps will extend the service intervals of vacuum pumps, by preventing contaminates from being ingested by the pump. Common applications for LPTA Series Traps are processes that produce significant amounts of dusts, powders, resins, etc. The polyester filter cartridge has an efficiency rating greater then 99%, and the filter cartridge is moisture resistant.
  • High Flow Design
  • Low Pressure Drop
  • Large Dirt Holding Capacity
  • ASA Flanged Inlet / Outlet

 

 

LPTA Series Inlet Traps

LPTA Series Inlet Traps feature right angle mounting arrangement, with ASA flanges for straightforward mounting, using ordinary hardware. Units are of steel construction, with a baked enamel finish, and are capable of withstanding hot air and oil mists. The filter itself incorporates a foam polyurethane "pre-filter" prior to the actual pleated, five (5) micron, polyester cartridge. This arrangement allows higher dirt carrying capacity (50%), thereby extending service intervals, as well as increasing uptime. Heavy duty "T" bolts allowing quick access for maintenance cycles, and ¼" female NPT ports are located on the inlet / outlet ports, allowing the use of gauges should the need arise.
