Wet Collectors & Wet Scrubbers
Wet collectors (commonly known as wet scrubbers too) are designed to capture and filter dust particles. Wet collectors adopt a self, wet scrubbing' motion to wet, capture and filter even the very fine dust particles from the air stream.
A wet extractor provides an efficient and effective way of disposing of obnoxious fumes and dust which arise within the workplace and are manufactured to cope with the heavy burden of flammable dust.
Wet scrubber dust collectors are renowned for their robustness and are unlike many other units available on the market. This is because they have few moving parts, filters or sprays to contend with which allows them to maintain their original suction pressure rates, even under the toughest of conditions.
How Does a Wet CollectorWork?
Wet collectors have a fan integrated into the top of each unit. They pull polluted air through an LEV system to capture dust particles through a wet collection method. The wet collector uses centrifugal forces to pull both contaminated air and water up through a series of fixed baffles (or also commonly known as scrubbers) from the water chamber located at the bottom of the unit.
Baffles are shaped as curved blades and as high-velocity air flows through the system, a scrubbing liquid solution curtain (consisting of thousands of water droplets) is created and captures even the finest of dust particles. The scrubbing solution is made up of a mix of water and a biocide to help prevent against legionnaires' disease.
Air is purified by mixing with the dust contaminated water with the scrubbing liquid droplets in the dust collectors to capture dust. As the droplets (containing captured dust particles) collide and are reintroduced with scrubbing solution in the baffles, the dense metal dust fall to the back down the baffles and are collected in the water chamber. An additional filtration layer ensures that small water droplets or water vapour doesn't reach the fan.
Wet dust settles at the bottom of the water chamber and creates a packed bed of sludge. This should regularly be collected, agitated and discharged via the water relief valve to reduce the risk of pressure drops. Clean air is discharged from the top of the unit back into the works atmosphere.

What Are Wet ScrubbersUsed For?
Wet system scrubbers are the ideal solution for filtering and collecting combustible dust produced from processes such as grinding, fettling, linishing, de-burring, polishing and trimming from metals such as Aluminium, Magnesium, Titanium, Zirconium, Lithium and Tantalum. Metal dust generated from these processes is classified as explosive.
Wet collectors mitigate the risk of dust explosions and fires, as if they were to form a cloud, they could ignite. Other combustible particulate matters include a wide range of materials, including, sugar, coal, wood, grain, certain metals, synthetic organic chemicals and any other material that can burn and exists in a fine powdered form. A wet extractor significantly reduces the risk of explosions and fires to keep workers safe - They'll also help you become HSE compliant.
Wet Scrubbers also meets OSHA and NFPA regulations for dust removal located inside buildings, they can recirculate in-plant, tempered air to conserve energy.
What do theHSEState?
In HSE’sHSG103: Safe Handling of Combustible Dust: Precautions Against Explosions, it states that: “Dusty areas will extend far away from the original source of dust release, as air currents will carry the finest of dust particles considerable distances and settle in high and low places. To prevent the dispersion of dust, the HSE recommends a local exhaust ventilation (LEV) system to capture dust at-source.”
Wet collection systems are mandated byNFPA (National Fire Protection Association) Standard 4842006 regulations for the effective filtration of potentially explosive metal dust. These controls are also often stipulated and required under theDangerous Substances and Explosive Atmosphere Regulations(DSEAR), the94/9/EC Directive(also known as 'ATEX 95' or 'the ATEX Equipment Directive') andControl of Substances Hazardous to Health(COSHH) Regulations 2002.
