Questions
Quick answers to the most common questions about setup, maintenance, filters, and safety.
Setup & Assembly
How long does it take to set up an inflatable paint booth?
A typical Sewinfla booth inflates and is ready to paint in under 5 minutes. The blower is the only powered component — unfold the booth, connect the inflation tube, plug in the blower, and the booth self-inflates. No tools, no frame assembly.
Do I need a dedicated power circuit?
Most Sewinfla blowers run on standard 110V–120V household outlets (US). Larger models with dual blowers may need two separate circuits. Check the blower specifications on the product page for your model. Always use a grounded GFCI outlet in wet or outdoor environments.
Can I set it up outdoors?
Yes — Sewinfla booths are designed for indoor and outdoor use. The 210D/420D Oxford fabric is UV-stabilized and water-resistant. For outdoor use, avoid wind speeds above 15 mph and secure the booth with the included ground stakes. Do not operate in rain or snow without overhead cover.
What surface can I set it up on?
Flat, level ground is ideal — concrete, asphalt, packed gravel, or grass all work. Avoid sharp objects, broken glass, or rough surfaces that could puncture the floor. We recommend laying a tarp underneath for added protection on rough surfaces.
Filtration & Ventilation
How often should I replace the filters?
The fiberglass pre-filter should be replaced every 3–5 full spray jobs or when visibly loaded. The activated carbon filter lasts 8–12 spray sessions (for typical solvent-based automotive paints). If you smell solvent odors at the exhaust, it's time to replace the carbon filter.
Does the booth come with filters?
Yes — every Sewinfla booth ships with one set of filters installed: a fiberglass pre-filter and an activated carbon exhaust filter. Replacement filter packs are available in our shop.
Is the filtration EPA-compliant?
Yes. The dual-stage filtration system (fiberglass pre-filter + activated carbon) meets EPA standards for professional spray environments. It captures 99.7% of airborne particulates and adsorbs VOC solvents including toluene, xylene, acetone, and isocyanates.
Do I need additional ventilation?
The integrated blower system provides continuous positive-pressure ventilation, exchanging the full air volume every 2–4 minutes. For enclosed indoor use (garage with the door closed), we recommend an additional exhaust fan venting to the outside. Always spray in a well-ventilated area.
Materials & Durability
What material is the booth made of?
Sewinfla booths use 210D or 420D Oxford weave fabric with a reinforced PVC coating, depending on the model. All seams are double-stitched with industrial-grade thread. The fabric is tear-resistant, UV-stabilized, and engineered for daily professional use.
How long will a Sewinfla booth last?
With proper care, a Sewinfla booth lasts 3–5+ years of regular professional use. The blower motor is rated for 3,000+ hours of continuous duty. Fabric life depends on UV exposure, frequency of use, and cleaning — wipe down overspray after each session to extend fabric life.
Can I repair a puncture or tear?
Yes — every Sewinfla booth includes a repair kit with PVC patches and adhesive. Small punctures can be patched in minutes without affecting performance. For larger damage, contact our support team.
