FRED™ C SERIES DUST COLLECTORS

FRED 02-02C Smoke and Fume Collector | Fred Filtration Industrial Air Cleaners, Collectors

HOW C SERIES DUST COLLECTORS OPERATE

Contaminated air enters the collector above the filter cartridges. Specially designed components in the cabinet uniformly distribute the contaminated air across the top of the filters.The contaminated air flows downward at a steady velocity. Dust is conveyed to the settling area below the filters by both air flow and gravity. Extremely small particulate is collected on the filter media, allowing clean air to return to the workplace or outside environment. Once particulate collection on the filters is sufficient to reduce air flow, the patented reverse jet pulse cleaning system propels the collected dust off of the filters and into the settling area.

DOWNFLOW:

The C Series downflow/verticle design produces zero velocity at the base of each filter stack, allowing the dust to settle uninhibited below the cartridges, thereby eliminating re-entrainment.

CARTRIDGE FILTERS:

The standard 80/20% cellulose/polyester cartridge media is high in resin content to provide mechanical resilience, and has pleat-lock construction. Standard cartridges are rated for temperature up to 160 degrees Fahrenheit. High temperature cartridges are also available.

DUST SETTLING:

The C Series design allows larger dust contaminates to have a clear path to the dust settling area and finer particles to be collected by the filters.

VENTURI:

Venturi reverse pulse cleaning is the quick release of pressure through a blow tube into a venturi enductor tube into a cartridge filter. A higher volume of air is induced via this principle. The resulting burst of compressed air is more equally dispersed across the filter resulting in greater cleaning effectiveness compared to typical reverse pulse cleaning.

FEATURE	BENEFIT
Cartridges arranged in a vertical orientation	Structural integrity of the ﬁlter is maintained Ensures consistent air -to-cloth ratio for each ﬁlter
Patented downﬂow/verticle airﬂow	Ensures uniform loading of ﬁlters while minimizing abrasion Process air assists cleaning action during online pulsing No-ﬂow area below ﬁlters acts as a settling chamber for dust Eliminates 90 degree ﬁlter rotation required maintenance
Custom Designed Inlet with duct velocities ranging from 2500 to 6000 FPM	Assures proper delivery of dust to the ﬁlters and helps maintain cleaner duct work
Small, solid weld tube sheet below vertical cartridge	Gasket seals are enhanced as ﬁlers load and the cartridge becomes heavier Eliminates potential for metal distortion and possible leakage
Solid welded construction separating clean air and dirty air plenums	Reduces potential for leakage
Reverse jet pulse design	Venturi-assisted to optimize cleaning effectiveness
Pulse valve silencers	Reduces system generated noise Supplied standard vs. optional by competitors
Programmable Amtech pulse control with digital pressure differential sensor	Allows for online and ofﬂine initiation of cleaning cycles Increases Filter Life and decreases costs Conserves compressed air

PULSE JETS:

Pulse jet performance and economy are maximized by Optimizing the orifice size and position. Pulse jet performance and economy are maximized by Optimizing the orifice size and position.

PULSE JETS:

The motor, fan and inlet cone are packaged into a tubular centrifugal fan arrangement for greater performance, quieter operation and simplified maintenance.

DUST COLLECTION EFFICIENCY:

The major obstacle to dust collection efficiency is re-entrainment, the refiltering of dust that has been stirred up prior to settling. The goal is to dislodge the dust from the filter and allow it to settle in the hopper below. The C Series utilizes patented downflow/verticle technology to minimize re-entrainment and extend filter life. Carefully managed inlet air velocity ensures that the air only flows downward, never upward or sideways. This prevents air movement below the filters where the dust has settled and results in effective cleaning while the dust collector is operating and shut down.

OPTION	BENEFIT
Side Inlet	Acts as dropout box for sparks Reduces overhead ductwork clearance requirements
Explosion Vent Door/Latches	Latches designed to release, eliminating replacement of expensive membrane panels
Custom Designed Inlet with duct velocities ranging from 2500 to 6000 FPM	Assures proper delivery of dust to the ﬁlters and helps maintain cleaner duct work
Centrifugal Partial Width Fan	Eliminates the need for volume outlet dampers
Fan Silencer	Reduces sound levels in order to comply with OSHA and EPA requirements
