Cartridge Filters for Dust Collectors
The Airtech Tong series cartridge is the replaceable filter inside an industrial pulse-jet dust collector. Pleated F6 cellulose media sits between a galvanised inner and outer mesh, so it holds its shape when the cleaning pulse hits it. It suits dry dust and compressor, blower and generator-set intakes. Two sizes are in stock in Pretoria.

The Airtech Tong series cartridge is the filter you replace in a pulse-jet dust collector or self-cleaning intake housing. It uses F6 cellulose media between a galvanised inner and outer mesh. The outer mesh matters: cellulose is soft, and the mesh holds the pleats in shape each time the cleaning pulse fires.
Both sizes (L600×OD324mm and L660×OD324mm) are in stock in Silverton, Pretoria, with nationwide delivery quoted at checkout on online orders. Cartridges are sold singly online, and volume orders can be quoted on request. Other sizes are made to order on a 7-10 working day lead time.
How a Cartridge Filter Works
A cartridge is a pleated filter tube. Dusty air passes from the outside in, the dust stays on the outside of the pleats, and clean air leaves through the open top. The pleats pack a lot of filter area into a small tube.
Every few minutes a short blast of compressed air fires down the inside of the cartridge. This pulse flexes the pleats and knocks the dust off into the hopper below, so the filter cleans itself and keeps running. Over time dust works into the media and the resistance (the pressure across the filter) climbs. When pulse cleaning no longer brings it back down, it is time to replace the cartridge.
For plant office and control room air handling at the same industrial facilities, Prebur also supplies G4 and F9 HVAC filters manufactured to EN779. View HVAC panel filter range.

Custom Cartridges to Specification
The two Airtech models above are the stocked line. Everything else is made to order against your specification: size, end caps and media.
- Media options: standard cellulose and spunbond polyester, plus PTFE-membrane media for very fine dust and fume, antistatic media for combustible dust, and water- or oil-repellent finishes for damp or oily dust.
- End caps and hardware: galvanised or stainless steel caps and mesh, with the cap style, seal type and fixing matched to your housing.
- Dimensions and pleat count: custom lengths, diameters and pleat counts built to your existing cartridge or housing drawing.
Media is chosen for your dust and conditions. Tell us the dust type and the operating temperature when you enquire. The stocked cellulose cartridge is for room-temperature duty.
Custom cartridges are quoted per specification. Get a Quote stating the size, end caps and media you need, or simply send the part number off your current cartridge.
The stocked F6 cellulose cartridge suits dry dust and machine intakes. Some dusts need a different media, made to order. Rule of thumb for stock: the dust is dry, not sticky, at room temperature and not combustible.
Good fit from stock
Self-cleaning pulse-jet intake housings in dry conditions. This is the duty the cartridge was designed for.
Metal fabrication shops. Dry, coarse to medium dust.
Dry, abrasive dust from blast reclaim systems, including Wheelabrator shot blast machines. Send the part number and we confirm fit before you order.
Non-combustible powders from bulk handling, dry crushing and screening.
Booths that throw overspray away rather than recover it.
Made to order
Cellulose soaks up moisture and clogs, and pulsing cannot clear it. Polyester media copes.
Hygiene and containment rules decide the media, so we quote on your full specification.
Needs antistatic media that bleeds off static charge. Your site safety assessment decides this.
Fume is too fine and sticky for F6. It needs a PTFE membrane or nanofibre media.
Cellulose holds too much powder. Meshless polyester lets it blow off cleanly between colours.
Turbines need a finer grade than F6: F7 to F9.
Will it fit my unit?
Send us the part number off your old dust collector filter or dust extraction filter, or a photo of the label and both ends. Add the make and model of your dust collector. We confirm fit before you order. Call Nick on +27 74 159 1634 or Get a Quote.
What is the difference between a baghouse filter and a cartridge filter?
A baghouse is the dust collection housing: the enclosure that contains the filtration elements and the pulse-jet cleaning mechanism. The cartridge filter is the replaceable filtration element inside it. Airtech Tong series cylindrical cartridge filters are the consumable element in pulse-jet baghouse systems, replaced when differential pressure across the housing stays high even after cleaning cycles.
How often should baghouse cartridge filters be replaced?
There is no fixed interval. Replace at 900 Pa, when pulse cleaning no longer brings the resistance back down. A dusty process gets there sooner than a light intake duty, so go by the pressure gauge, not the calendar.
Will your cartridge fit my dust collector?
Send us the part number off your current cartridge, or a photo of the label and both ends, plus the make and model of your collector. We confirm fit before you order.
