Accessories & Consumables

Seventeen Part Numbers, Built to Work Together

Seventeen accessory and consumable part numbers, stocked — five blower power classes, three Air Draft Device sizes, a 12” 520 W axial exhaust fan, and eight filter part numbers including a cut-to-fit roll. Most inflatable-booth sellers ship one blower and one filter size and move on. This range exists because one blower and one filter cannot serve both a 13 ft garage booth and a 90 ft pressure vessel booth — and because a booth you cannot buy parts for is a disposable, not a tool.

Blowers Airflow & exhaust Filters & consumables Compatibility Replacement schedule

Blowers — five power classes

Inflation and circulation are different jobs. One blower holds the booth rigid; a second drives air through the filters and clears overspray. Stocking five power classes means the package is sized to the booth and the coating, not inherited from whatever came in the box.

BlowerPriceTypical use
480W Air Blower$79.99Compact booths and small parts; the low draw option for shared circuits
550W Air Blower$89.9913 ft class booths; inflates a compact booth in under a minute
750W Air Blower$119.9920 ft class inflation, or the exchange blower on mid-size booths
950W Air Blower$145.9926 ft and larger; the standard second blower for active exchange
1100W Air Blower$155.9939 ft+ booths, multi-blower arrays and continuous-inflation large builds

Motors: compliance documentation available on request. Run a new blower for five minutes outside the booth before first use to clear manufacturing lint, and put blowers on a dedicated 15 amp circuit.

Airflow & exhaust — what makes a garage usable

PartPriceWhat it solves
MINI Air Draft Device
Elephant Trunk		$99.00Small and compact booths — routes indoor exhaust to a window so you can paint inside
Air Draft Device (Standard)$229.99Mid-size booths; the component most owners add when overspray hangs in the air
Oversized Air Draft Device$299.99Large and custom booths; high-volume extraction at fume-accumulation height
12” Exhaust Axial Fan, 520W
with 16.5 ft duct		$239.04Adds powered extraction to a booth that ships with filtration only — the fix for lingering fog

Position the intake and the exhaust on opposite sides of the booth. Owners who fit powered extraction report the fog clearing within roughly a minute of spraying instead of hanging for the session.

Filters & consumables — eight part numbers

Filters are consumables, not lifetime components. Running a saturated filter is the number-one cause of reduced booth pressure, poor extraction and solvent odour breakthrough — and it is the point at which owners of generic booths discover that replacement media cannot be bought.

PartPriceFits / use
Small Replacement Filter$69.99Compact booths and personnel chambers
Oversized Replacement Filter$79.99Large booths; the standard-pattern pad for bigger filter windows
Industrial-Grade Replacement Filter (2 pcs)$69.99Particulate pre-filtration ahead of the carbon layer
Activated Carbon Filters (2 pcs)$69.99Adsorbs solvent vapour and odour — the layer that matters indoors
Replacement Filter Set
Particulate + activated carbon		$119.99The two-stage set — buy this if you change both layers together
Super Large Double-Layer Filters
51 × 102 in		$189.99Sewinfla airtight PVC booths and large filter windows
Fiberglass Filter Roll
3 ft × 66 ft, cut-to-fit		$132.99Any booth with removable filter windows — filter size is never a dead end
Airbrush Spray Booth Filter Set$39.99Airbrush and small-scale booths

The cut-to-fit roll is deliberate. Proprietary filter sizes are how owners get locked into one supplier at whatever price; a 3 ft × 66 ft roll that you cut to your filter window means the booth outlives the seller's catalogue.

Guidance, not a rule. Airflow should be sized to the coating chemistry and the booth cross-section — send us those two numbers and we will specify the package in writing.

Replacement schedule

ConsumableReplace when
Fiberglass pre-filterEvery 3–5 full spray jobs, or at 60% visible loading — the pre-filter set lists at $39.99 and the alternative is a ruined finish
Activated carbon mediaSeasonally in normal use — or when the exhaust still smells of solvent after a rest period
Industrial-grade particulate layerWith the pre-filter, or when it visibly loads ahead of the carbon
BlowerOn failure or thermal cut-off; keep one spare if the booth is on billed work

Symptoms of a loaded filter, before you inspect it: booth walls sagging during spraying, overspray haze lingering beyond about 15 seconds, and a blower housing that is uncomfortable to hold for more than three seconds. All three mean restricted airflow.

Where these intervals come from

  • 40 CFR § 63.11173(e)(2)(i) requires the filter of a spray booth to be demonstrated to capture at least 98% of paint overspray by weight, tested to ANSI/ASHRAE 52.2-2017. That figure describes media in its tested condition — a loaded pad is outside the condition it was measured in, which is why the replacement interval is a compliance input and not housekeeping preference.
  • OSHA 29 CFR 1910.107(b)(5)(ii) directs that filter pads be removed and placed in a water-filled metal container at the close of the day's operation, or otherwise deposited immediately in a safe location. Used media is a regulated waste stream whatever it looks like.
  • OSHA 29 CFR 1910.107(b)(5)(iii) requires filters to be installed so that they do not reduce the effective enclosure area of the booth. A pad that blocks the return path is a compliance problem as well as an airflow problem.
  • Where a figure is a catalogue value rather than a regulation — blower wattages, prices, and the replacement cadence itself — it is Sewinfla's own listed value, printed on this page.

Sources checked 16 October 2026: Cornell LII 40 CFR § 63.11173 (98% capture, filter requirements, ANSI/ASHRAE 52.2-2017 test method); OSHA 29 CFR 1910.107 (filter media disposal, filter placement, airflow).

Upgrading a booth you already own

You do not have to replace a booth to fix its airflow. The blower and exhaust range uses standard patterns and works with many inflatable booth designs, and the cut-to-fit fiberglass roll fits any booth with removable filter windows regardless of brand. If you own another make and need a specification, send us the booth dimensions, the filter window size and the coating you use, and we will match the package — including telling you if the fix is simply a second blower rather than anything else.

Why we stock this much

Because a booth is only as good as its parts chain. A single blower and a single filter size force every owner into the same compromise; stocking five blower classes, three extraction devices and eight filter part numbers is what makes "specified to the application" possible rather than a tagline. It is also why owners of other brands come here for consumables — and why a Sewinfla booth stays serviceable years after an unbranded listing disappears.

Accessory Questions

Spares, filters and fit

What buyers ask before ordering replacement parts: which numbers are stocked, how often the filtration media is changed, and whether a component fits a booth we did not build.

Does Sewinfla sell replacement parts for inflatable paint booths?

Yes. Seventeen accessory and consumable part numbers are stocked: five blower power classes (480W, 550W, 750W, 950W, 1100W), three Air Draft Device sizes (mini, standard, oversized), a 12-inch 520W axial exhaust fan with duct, and eight filter part numbers including individual replacement filters, a two-piece industrial-grade particulate set, activated carbon pads, a super-large double-layer 51x102 inch set, and a 3 ft x 66 ft cut-to-fit fiberglass roll.

How often should inflatable paint booth filters be replaced?

Replace the fiberglass pre-filter every 3 to 5 full spray jobs, or sooner once visible loading passes about 60 percent of the surface, and replace the activated-carbon main media seasonally. A loaded pre-filter raises static pressure at the blower intake, which is what makes a booth sag and mist linger rather than clear.

Do Sewinfla accessories fit other brands of inflatable booth?

The blower and exhaust range is standard-pattern and works with many inflatable booth designs, and the cut-to-fit fiberglass filter roll fits any booth with removable filter windows regardless of brand. Filter pads cut to a proprietary size, and booth-specific hardware, are matched to Sewinfla builds; send dimensions and we will confirm before you order.

Do I need a second blower or an exhaust fan?

For anything larger than small parts, yes. A single blower must both hold the structure inflated and drive air through the filters, and that split duty is the root cause of most ventilation complaints. A dedicated second blower plus powered exhaust is what clears overspray while the booth stays rigid.

Why does Sewinfla stock this many accessory variants?

Because one blower and one filter size cannot serve a 13 ft garage booth and a 90 ft pressure vessel booth. Selling the component in the grade the application needs is what makes a matched system possible, and stocking spares for years is what keeps a booth serviceable instead of disposable.

Not sure which part you need?

Send your booth dimensions, filter window size and coating type. We will specify the blower, extraction and filter package in writing.
