Sankair Paint Booth Exhaust Fiberglass Filter Pad
The Sankair filter pads come in a 20″ x 20″ size with green and white faces to indicate airflow direction clearly. The lightweight fiberglass media aids quick installation, and the product aligns with environmental standards for spray booth exhaust filtration. Best for teams needing clear orientation during setup and straightforward compliance. Limitation: installation accuracy matters for optimal performance.
AUC Paint Booth Exhaust Filters 20″ x 20″ (50/Case)
These AUC 20″ x 20″ exhaust filters use 15-gram fiberglass media for solid overspray capture. The green side faces the spray booth and the white side faces the air outlet, aiding correct installation. Best for budget-conscious shops that still require reliable filtration and easy replacement. Data note: actual dimensions are listed as 20.5″ x 20.5″, which should be accounted for in fitting.
LAUCO 20″ x 20″ x 2″ Filter Pad
LAUCO’s 20″ x 20″ x 2″ pads use 18-gram fiberglass media for superior paint trapping. The design emphasizes reduced maintenance by preventing particle buildup in fans and ducts. Best for high-volume shops needing robust filtering. Caution: handle with gloves and long sleeves during handling.
Master Elite Premium Filter Roll, 20.5″ x 100′
The filter roll provides a long, continuous filtration surface for larger booths. At 20.5″ by 100 feet, it suits installations where a rolling approach reduces downtime and simplifies maintenance. Best for large finishing booths or facilities with steady, high-volume spraying. Limitation: replacement requires careful measurement to avoid gaps in filtration.
PRISTAIR Spray Booth Capture Filter
The 20″ x 20″ PRISTAIR filter uses 15-gram fiberglass media and a color-coded green/white direction system to simplify correct orientation. It captures ≥95% of paint particles, helping protect downstream equipment and meet workshop standards. Best for operations prioritizing high particle capture with clear setup indicators. Caution: ensure proper fit with your specific booth model.
AUC Paint Booth Tacky Intake Filter Series 55
This intake filter uses a tackified polyester media on an internal wire frame for robust intake filtration. The two-ply design increases adsorption capacity, trapping larger particles first, then finer dust with tack. Best for shops needing stable intake filtration that resists collapse. Limitation: internal frame requires proper handling during replacement to maintain seal integrity.
HITON Paint Spray Booth Exhaust Filter Pad
HITON offers a 100-pack exhaust filter pad designed for all-purpose use in paint booths. It suits cross-draft and down-draft systems and provides a broad particulate capture range. Best for shops needing economical, high-volume replacement options. Caution: verify fitment for exact booth dimensions before purchase.
Buying Guide: Key Purchase Considerations
- Filtration media weight: Heavier fiberglass (around 18 g) generally traps more overspray but may require careful handling and installation.
- Booth compatibility: Verify actual dimensions, including any listed variations (e.g., 20.5″ x 20.5″ or 20″ x 20″ with thickness) to ensure a proper seal.
- Side orientation and color coding: Some pads use green/white with directional cues to reduce installation errors.
- Intake vs exhaust: Intake filters protect incoming air; exhaust filters trap paint particles before exhaust. Choose the correct type for your system.
- Maintenance interval: Heavy-traffic shops need filters with higher holding capacity and easier replacement procedures to minimize downtime.
- Compliance and safety: Materials should meet local environmental standards; consider gloves and protective gear when handling fiberglass media.
- Cost and replacement cycles: Compare price per filter and per lineal foot for rolls to estimate ongoing costs accurately.
Frequently Asked Questions
What size should spray booth exhaust filters be?
Most common sizes are 20″ x 20″ for exhaust pads and 20.5″ x 20.5″ for some models. Confirm your booth’s housing dimensions before purchasing.
Is heavier fiberglass better for filtration?
Yes, 18-gram fiberglass generally provides stronger paint particle capture, but it can be less forgiving to install and handle.
Should filters be green on one side and white on the other?
Color-coded designs help ensure correct orientation, which improves filtration efficiency and ease of setup.
When should I replace exhaust filters?
Replace when the media is visibly saturated, airflow drops, or maintenance schedules indicate replacement. Higher volume shops may need more frequent changes.
Are intake filters different from exhaust filters?
Yes. Intake filters protect the building air and filter larger particles before they enter the booth, while exhaust filters capture overspray from the finishing process before exhaust.
Do these filters require special handling?
Fiberglass media can irritate skin; wear gloves and long sleeves during handling and replacement.
