The Airtech Tong series cartridge filter is the replaceable filtration element inside pulse-jet baghouse dust collectors. F6-rated cellulose media in a rigid galvanised steel mesh frame (inner and outer), engineered for repeated pulse-jet cleaning cycles without deforming. Two standard sizes cover the most common baghouse housings in South African industry. A stainless steel frame option is available for corrosive environments.
Both standard sizes (L600×OD324mm and L660×OD324mm) are held in stock in Silverton, Pretoria, with free nationwide delivery on online orders. Cartridges are sold as single units online, and volume requirements can be quoted on request. Custom sizes are manufactured on a 7-10 working day lead time.
What Is a Baghouse / Cartridge Filter?
A baghouse is a dust collection unit used in factories, foundries, and processing plants. It captures airborne dust from production processes and collects it in a hopper below. The filter cartridge sits inside the baghouse and does the actual work, trapping dust particles as air passes through. Over time, dust builds up on the filter surface and restricts airflow.
Most industrial baghouses use a pulse-jet cleaning system. Compressed air fires in short bursts through each cartridge on a timed cycle, knocking the dust off the filter surface and dropping it into the hopper. This extends the cartridge's working life significantly. One filter goes through many cleaning cycles before it needs replacing. You know it is time to replace the cartridges when the pressure across the baghouse stays high even after a cleaning cycle. At that point, the filter media is loaded and pulse-cleaning can no longer restore performance.
Tong Series Cartridge Filters
The Tong series covers the two most common baghouse housing sizes in South African industrial applications. Both models use cellulose filter media with a galvanised steel mesh structure (inner and outer), built to handle repeated pulse-jet cleaning without deforming. For corrosive environments such as galvanising lines, acid handling, and surface treatment, a stainless steel frame option is available.
Not sure if the Tong series fits your housing? Send us the outer diameter, length, and housing manufacturer and we will confirm compatibility or advise on alternatives. Prebur can cross-reference competitor part numbers against the Tong series to confirm a fit before you commit to an order.
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, for both air and wet filtration duties.
- Media options: standard cellulose and spunbond polyester, plus PTFE-membrane media for sub-micron dust and fume, antistatic media, and water- or oil-repellent treatments for damp, hygroscopic or oily dusts.
- End caps and hardware: aluminium or galvanised end caps, 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 selected against your operating environment. State the dust type and the operating temperature when you enquire: cellulose runs to about 70°C continuous, synthetic media substantially higher, and the applicable limit is confirmed on the media specification for your order.
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.
Airtech Tong series baghouse cartridge filters are supplied to industrial facilities across South Africa. The F6 cellulose media and robust galvanised steel frame make these filters suited to a wide range of dust types and operating environments.
Dust extraction on crushing, screening, and conveyor transfer points. Baghouse filtration captures fine mineral particulate before it enters the working environment or atmosphere. High dust loads make local stock and fast delivery essential.
Fine limestone and clinker dust demands robust filtration at high airflows. Pulse-jet baghouses are standard in cement production; cartridge replacement is a scheduled maintenance item. Tong series cartridges handle the dust load and cleaning cycles in these high-throughput environments.
Sawdust, wood chips, and fine sanding dust are captured by baghouse dust collectors on saws, planers, and sanders. F6 cartridge filtration is appropriate for the particle size range produced by most woodworking equipment.
Grain handling, flour milling, and sugar processing generate combustible dust that requires careful extraction and filtration. Baghouse systems with pulse-jet cleaned cartridge filters are the standard solution for food industry dust control.
Active ingredient dust and excipient particulate from tablet presses, granulators, and coating lines is captured by dedicated baghouse systems. Cartridge filtration maintains clean air in controlled production environments.
Grinding, cutting, and welding fines from metal fabrication, plus metallic shot reclaim dust on Wheelabrator shot blast machines. Tong series cartridges are a direct cross-reference for common Wheelabrator housing sizes. Stainless frame available for corrosive environments.
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?
Replace at a differential pressure of 900 Pa when pulse-jet cleaning can no longer restore performance. In high-dust-load applications such as foundries and cement plants, replacement intervals of 6–12 months are typical. Low-dust applications may run considerably longer. Monitor differential pressure rather than using time-based replacement intervals.
