• Standard Final Filters The basic housing is designed for standard 24' x 24" x 11½" HEPA filters or carbon adsorber cells. LENGE designs and manufactures a full line of HEPA filters and adsorber cells. Filters include highcapacity HEPA filters for service up to 2,000 CFM each.

Containment System:

• Three Filters Per Door

  Units up to three filters wide are serviced through only one door. Two doors are furnished with units four through six filters wide, one on each side of the housing.

• External Locking Mechanism

  All gasket seal filters and adsorbers are furnished with a replaceable clamp type locking mechanism which is actuated from outside the housing. Filter seals can be “fine-tuned” as needed without opening the door. An optional security device is available to turn an external locking mechanism into an internal locking mechanism.

  This requires that the door be opened for the locking mechanism to be activated.

• Filter Module

  Pre filter -- Panel filter G4

  HEPA filter -- Gel sealed mini-pleated HEPA filter H14
