Airtech G3 filter media is a white non-woven polyester roll for coarse first-stage filtration. It catches coarse dust and debris ahead of coils and finer filters, and it cuts to any shape with a blade or scissors.
The 2 m × 20 m roll (40 m²) is held in stock in Silverton, Pretoria. We deliver nationwide, with the delivery price quoted for your address at checkout, or you can collect. Online orders are sold in full rolls. For larger quantities, request a quote.
Roll media or a framed panel?
A G4 panel filter is a rigid framed unit in fixed sizes, and it is the right choice wherever the housing takes a standard panel. Roll media is for the housings that no stock panel fits: non-standard frames, wire-frame holders, large intakes and filters you build yourself.
G3 is one grade coarser than G4. The trade-off for the flexibility is lower efficiency: it does not replace a G4 panel where the housing takes one, and it is not a substitute for finer filtration further down the system.
Ordering
The media is sold by the full roll, with no minimum beyond one roll. 2 m is the only width. Add rolls to your cart above, or call Nick on +27 74 159 1634 for larger quantities.

Use G3 roll media for coarse pre-filtration where a framed panel does not fit.
When a housing or wire-frame holder does not match any stock panel size, cut pads from the roll to the exact size, on site or in advance.
Fit a sheet over a large air intake on a support grid to catch coarse dust and debris before it reaches coils and finer filters.
Filter makers use the roll as base media, cutting and framing it to their own designs.
What does G3 mean on this media?
G3 is a coarse grade: the media catches coarse dust and debris ahead of coils and finer filters. It is one grade coarser than a G4 panel. It does not replace a G4 panel where the housing takes one, and it is not a fine filter.
What size is a roll?
Each roll is 2 m wide × 20 m long (40 m²), nominal 6-7 mm thick, and weighs about 2,9 kg. Every roll comes in its own sealed bag. 2 m is the only width.
Can I order a partial roll?
No. The media is sold in full rolls only, with no minimum beyond one roll. Buy as many rolls as you need online, or call for larger quantities.
How do I cut and fit it?
It cuts to any shape with a blade or scissors. Cut pads to the size of a non-standard housing or wire-frame holder, or fit a larger sheet over an intake on a support grid. Replace it when it is visibly loaded, or at your scheduled change-out.
What temperature can it take?
The manufacturer rates the media at 100 °C continuous and 120 °C peak.
How should I store the rolls?
Indoors, dry and out of direct sunlight, laid flat or standing upright with support.
