Description

 Camfil Farr Gold Series 20 Cartridge Dust Extractor

The ATEX-classified Camfil APC Dust Collector is designed for collecting and filtering ex- plosive and non-explosive dry dust. 

The Gold Series® industrial dust collector rids work environments of hazardous and nuisance dust and fumes/smoke with the smallest floor space of any collector available today. Heavy-duty carbon steel construction and thermal cured powder coatings provide unparalleled strength and durability.

Definitions

m3/h
Actual m3 of gas per hour. The volume of gas flowing per hour at the operating temperature, pressure, elevation and composition.

Air-to-Cloth Ratio The ratio between air flowing through a dust collector and the m2 of filter area available (m3/m2 h). Sometimes referred to as the velocity (m/h) of air through the cloth.

Blinding
Blockage in a fabric or media by dust that cannot be discharged by the cleaning mechanism, resulting in a reduced gas flow and an increased pressure drop across the media. Once enough material has built up, airflow is severely restricted and the bags have to be cleaned or replaced.

Bridging
Material handling problem characterized by the particulate forming a cavity over the discharge or opening of a hopper or storage vessel. Also, the accumulation of collected dust between two or more filter elements.

Clean Air Plenum
The dust collector area, through which gases are directed, located on the clean side of the filter media.

Collection Efficiency
The measure of a dust collector’s ability to remove particulate from the inlet gas, typically expressed in percent or emission rate (mg per cubic meter).

Dew Point
The temperature at which condensation begins to form as the gas is cooled.

Differential Pressure
The change in pressure or the pressure drop across a device. The difference between static pressures measured at the inlet and outlet of a device,
Ref. Pressure Drop.

Dust Cake
A dust build-up on the filter elements that increases the efficiency of the filter media.

Diaphragm Valve
A compressed air valve operated by a solenoid valve that opens to allow a pulse to a row of filters.

Dust Loading
The weight of solid particulate suspended in an air stream, usually expressed in mg per cubic meter.

Emissions
Particulate that escapes through or around a dust collector into the atmosphere.

Negative Pressure System
A system where the fan is located after the dust collector on the clean air side, pulling air through the system.

Positive Pressure System
A system with a fan located prior to a dust collector on the dirty side, pushing air through the system.

Precoat
Material added to the air stream at start-up to aid in establishing the initial dust cake on the filter media.

Rotary Airlock Valve
Device having a star wheel (rotor) designed to provide an air tight seal between the negative or positive pressures of the collector and the outside atmosphere.

Screw Conveyor
A revolving screw operating in a fixed trough for conveying material from one point to another.

Pulse Duration (On-Time)
The length of time a pulse lasts, generally described as the length of time the electric signal holds the solenoid pilot valve open (fixed at 150m/s).

Pause Time (Off-Time)
Elapsed time between pulses in a dust collector cleaning system.

Solenoid Valve
An electromechanical plunger device that is either “normally open” or “normally closed”. In use with a dust collector, it is for the relief of air pressure to activate a compressed air device such as a diaphragm valve.

Tube Sheet
A steel plate on which the open end of the filter elements are connected. This wall separates the clean air and dirty air plenums of the dust collector.
