The LENGE Bag In/Bag Out side access filter system is a safe,
simple, reliable method for removing contaminated particulate
filters and/or gas absorbers used for air purification in hazardous
environments. With this system, maintenance personnel are protected
from coming in direct contact with the interior of the housing and
hazardous contaminants during filter change-out.
Characteristics and Features:
Manufactured from powder-coated cold-rolled sheet or 304 stainless
steel and 316 stainless steel for option.
Deep Adsorber Housing: Housings are available for 12", 16"and 18"
filter cells. When additional residence time is required, these
units can be furnished in series, or operated at lower face
velocities.
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.
