Blowtherm Extra Filter Fitments
The Extra is Blowtherm's mid-tier collision booth, Italian-built with the brand's European downdraft conventions and a scaled-back version of the heat-recovery integration that defines the World flagship. Where the World targets premium MSO and high-end dealer-channel installations, the Extra serves a broader population of US collision shops looking for European engineering at a more accessible price point. The fitment family follows the Blowtherm downdraft pattern with verified records drawn from authorized-dealer cross-references and provenance disclosed up front.
Quick answer
The Blowtherm Extra is the Italian-built mid-tier model in Blowtherm's collision lineup, European downdraft design with the brand's signature heat-recovery integration, positioned below the flagship World line. Source confidence on this fitment is authorized-dealer cross-reference, kit ships with quote-back form to upgrade to field-verified before subscription auto-renews.
How Extra shops choose filters
Intake side. The Extra follows European downdraft conventions, pressurized intake plenum with ceiling-mounted polyester or fiberglass diffusion media in the panel grid. The panel set is sized to the Extra's footprint, smaller than the World's flagship configuration. We don't fabricate ceiling dimensions; the verified-fitment record draws from authorized-dealer cross-references and is confirmed by the nameplate plus a ceiling-panel photo. AMU pre-filter handling on the Extra includes the heat-recovery loop's pre-filter stage, typically a single-stage panel rather than the bag-and-panel combination on the World.
Exhaust side. The Extra uses Blowtherm's downdraft exhaust-pit slot family with pad-mounted media. Catalog default is fiberglass arrestor pad with polyester arrestor as the upgrade for higher-solids and waterborne work. The 25-entry filter media taxonomy on this site distinguishes the 12 exhaust types, fiberglass-arrestor, polyester-arrestor, accordion-paper, paper-mesh, pocketed-paper, cube-overspray-arrestor, tower-exhaust-pocket-bag, plus 5 more, alongside 9 intake types and 4 specialty types. The Extra's verified-fitment kit names the specific media-type slug per slot.
Slot expectations are queued for re-mapping. A note on transparency: the booth-model slot expectations row for the Extra in our database is currently flagged in the verification queue as pending re-mapping against the new 25-entry media taxonomy (the platform expanded from 9 to 25 media types on 2026-05-09). The kit you receive is correct, we're updating the metadata record, not the physical fitment.
Cycle math. Independent collision shops on the Extra typically run intake-ceiling at 35-50 days, AMU pre-filter at 55-85 days (heat-recovery loop loads the AMU faster than non-recovering booths), exhaust-pit pad at 75-105 days. MSO installations cycle tighter. Subscriptions auto-tune by ZIP, volume, and heat-recovery configuration.
Regulatory landscape
Extra installations run under standard regulatory layers, state DEP authority plus regional AQMDs, plus federal OSHA spray-finishing standards (29 CFR 1910.94). Most independent shops with an Extra fall under 6H Area Source category under NESHAP Subpart HHHHHH, which requires booth operation and maintenance per manufacturer specification with documented filter changes. Italian-design capture-efficiency documentation maps cleanly to US AQMD requirements when matched to the original-equipment fitment kit; verified-fitment kits in our catalog maintain the original capture rating per the OEM specification.
Who runs the Extra
Two populations dominate the Extra installed base. First, mid-volume independent collision shops looking for European engineering and the heat-recovery operating-cost benefit at a more accessible entry price than the World flagship. Second, dealership body shops in mid-tier markets where the Blowtherm dealer-channel relationship pulled the Extra into a packaged installation but the World wasn't required.
Extra filter FAQs
How do I confirm I have an Extra versus a World?
The Blowtherm nameplate carries the model designation. The World is identifiable by its more elaborate AMU pre-filter bag stage and the larger ceiling-plenum geometry; the Extra has a simpler AMU configuration. If the nameplate is illegible, the Filter Finder accepts a photo of the AMU stage and ceiling for confirmation.
What's the source confidence on this fitment, and what does that mean for me?
**Distributor-cross-ref**, currently. That means the kit dimensions and slot count come from authorized-dealer parts cross-references in our authorized-dealer cross-reference import, high-confidence but not yet field-verified. The first kit shipment includes a measurement quote-back form. When you paste back your verified measurements, the record upgrades to field-verified and your subscription locks in. If your measurements differ from the cross-ref data, we ship a corrected kit at no charge.
Why are the manuals for my Extra so hard to find?
Blowtherm is Italian-parented with manuals originally drafted in Italian and translated for the US distribution channel. The current-generation manuals are gated through the MyBlowtherm customer portal rather than as public PDFs. We're honest about this, the manual access path runs through your Blowtherm USA dealer relationship, not a public download. Our verified fitments come from authorized-dealer cross-references and don't require manual access to specify correctly.
Does heat recovery on the Extra change my filter cycle?
Yes, on the AMU pre-filter side. The heat-recovery loop concentrates particulate before the make-up air return, which loads the AMU pre-filter faster than non-recovering booths. The cadence on the Extra's AMU is tighter than equivalent non-recovering installations, subscriptions tuned for Blowtherm heat-recovery configurations account for this.
Can I run waterborne paint through the Extra?
Yes, with the polyester arrestor upgrade on the exhaust pad. Waterborne work loads fiberglass arrestor pad faster than solvent-based work; the polyester upgrade extends the cycle. The heat-recovery loop on the Extra handles waterborne moisture loading in the AMU return path without modification.
Is the Blowtherm dealer network in my region able to support service on the Extra?
Blowtherm USA's dealer footprint covers the major US collision markets. Dealer-channel service for the Extra is generally available in metropolitan and second-tier markets; rural or remote installations may have longer service-response times. Filter supply through this catalog is independent of the dealer service network, your fitment kit ships direct on the subscription cadence regardless of dealer geography.
