Here are a few dust collector terms for begginners.
Bleedthrough – Dust or fume particles that are able to migrate through a bag.
Blinding – A closing of the filter pores which as a result, causes either a reduced gas flow or an increased pressure drop across the medium.
Damper – Dampers are used in dust collection systems in order to control the airflow to specific branches of the ductwork. You can do this by simply opening or closing the damper.
Dust Cake – During the filtration process it refers to dust formation developed on the surface of the filter.
Filtration – Separation of particles from a fluid stream by use of a penetrable barrier.
Hood – A shaped inlet designed to capture contaminated air and conduct it into the exhaust dust system.
Hopper – All dust collectors include a hopper that collects the captured dust. The storage of dust is not the intention of a hopper. They are there for the dust to collect until it passes out of the dust collector through an airlock.
Magnehelic Gauge – An instrument used to measure the differential pressure drop in a bag house.
Micron – A unit of length, the thousandth part of 1 mm or the millionth of a meter.
Photohelic Gauge – An instrument that measures differential pressure and adjustable set points control it.
Pulse Frequency – The time between pulses in a pulse-jet baghouse.
Re-Entrainment – The re-depositing of dust on the filter bag surface after it has been pulsed off.
Stack – You can use stacks in conjunction with fans to vent air into the atmosphere. Their design usually makes it protrude from the roof line so wind can disperse it.
Static Pressure – The negative or positive pressure on the components of a system.
Surface Filtration – The filter surface that particulate is captured on.
