GUANLIN paint booth intake pre-filter, G3 G4 panel filter protecting booth supply air and downstream media.
G3/G4 primary panels for spray booth intake plenums, protecting ceiling diffusion media and downstream filters from coarse dust and insects.
Description
A spray booth has two filters that matter financially: the ceiling diffusion media that defines finish quality, and the exhaust arrestor that defines how often the booth is down for cleaning. Both are protected by the same cheap component — the intake pre-filter. Skip it or change it late and the ceiling media loads with pollen and dust, and every panel sprayed afterwards carries the defect.
Why Choose GUANLIN Booth Intake Pre-Filters
- Protects ceiling media — removes coarse dust, pollen and insects before the diffusion layer.
- G3/G4 options — matched to ambient dust load.
- Rigid paper frame — holds shape in the intake plenum.
- Low resistance — preserves booth supply airflow and pressure balance.
- Cost effective — the cheapest component protects the most expensive ones.
- Custom sizes — to your intake plenum.
