Cartridge Filters for Baghouses and Dust Collectors — Tong Series, South Africa

What Is a Baghouse and Why Do Cartridge Filters Matter?

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 — F6 Rated, Pulse-Jet Cleanable

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 — galvanising lines, acid handling, 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. We will confirm compatibility or advise on alternatives.

Industries We Supply — Baghouse Filters for SA Industry

Prebur supplies Tong series baghouse filter cartridges 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.

• Foundries — Metal casting generates high dust loads of fine metallic and refractory particulate at elevated temperatures. Baghouse filtration on casting and shakeout lines is a regulatory requirement. High replacement frequency makes local stock critical.
• Metal fabrication — Grinding, cutting, and welding fines are captured by baghouse dust collectors before they enter the workshop atmosphere. F6-rated cartridge filters handle metalworking dust across a broad particle size range.
• Cement plants — 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.
• Automotive manufacturing — Metalworking, paint booth pre-filtration, and general production dust are managed by baghouse systems on automotive lines. Fast-turnaround local stock fits planned shutdown maintenance windows.
• Surface treatment and galvanising — Corrosive dust from acid pickle lines and zinc bath operations requires stainless steel mesh construction. The Tong stainless option is specified for these environments.
• Wheelabrator shot blast machines — Shot blast reclaim dust collectors on Wheelabrator machines use cylindrical cartridge filters as the primary filtration element. Tong series cartridges are a direct cross-reference for common Wheelabrator housing sizes.

Note: Prebur also supplies EN779-certified G4 and F9 HVAC filters to the same industrial facilities — for AHU pre-filtration, plant office air handling, and control room pressurisation. View HVAC filter range.
