What We Stock

Prebur is an owner-run air filtration supplier, trading from Silverton, Pretoria for 37 years. Our Airtech range is stocked in standard sizes: G4 panel pre-filters, F9 pocket filters, F9 V-Bank filters, H14 HEPA terminal filters, and F6 cartridge filters, with pulse cartridge and dust-collection filters for industrial applications.

Airtech is not all we sell. We also supply carbon filters, mesh and wire-mesh filters, filter frames and clips, and filter media, and our air quality testing service verifies the filtration you run. One supplier for the whole airflow chain.

Who We Supply

HVAC contractors rely on G4 and F9 supply from local stock. Healthcare facilities run ward ventilation through to theatre-grade HEPA. Pharmaceutical manufacturers need H14 HEPA with individual EN1822 test certificates. Industrial plants need cartridge filters that survive daily dust loads. Same supplier, different specifications.
