PFS ZENITH SERIES Full downdraft airflow. ETL listed (Intertek) for the USA and Canada. UL 508A controls. Built to NFPA 33 standards. No concrete pit — raised steel floor plenum sits on your existing slab. Standard sizes 14’W × 9–12’H × 24–33’L.
Air enters through a full ceiling plenum and flows straight down — identical to a concrete-pit full downdraft. The difference is at the floor: instead of exhausting into a pit poured into the slab, air enters a raised steel plenum sitting on top of your existing concrete, then travels through the duct to the exhaust stack.
Custom sizes available. Contact your PFS engineer for custom sizing and raised floor specifications.
Add a direct-fired or indirect-fired heat system to your raised-basement downdraft booth for accelerated cure times. Blanket intake filter upgrades included with all heated configurations.
Maximize throughput and compliance by pairing your raised-basement booth with a dedicated mixing room for paint prep and an air make-up unit for tempered make-up air.

Filtered air enters through a full-length ceiling plenum and moves straight down over the vehicle or part. Instead of dropping into a pit cut into the slab, the air passes through steel floor grates into a raised steel plenum that sits on top of your existing floor, then travels to the exhaust fan and stack.
You get the same top-to-bottom airflow as a pit-style full downdraft booth: overspray is pulled down and away from the painter’s breathing zone and away from freshly painted panels.
A concrete pit gives a flush floor but means saw-cutting, excavation, drainage and structural work, often with a separate permit and weeks of downtime. A raised basement skips all of that: the booth bolts together on the slab you already have, and it can be relocated later if your shop moves.
The trade-off is floor height. The grated floor sits above the surrounding slab, so vehicles and carts roll in over a short drive-on ramp.
PFS Zenith raised basement booths are built 14 ft wide with 9, 10 or 12 ft interior height and 24, 27, 30 or 33 ft lengths. Custom widths, heights and lengths are engineered for larger vehicles and equipment. Plan for the raised floor and the exhaust stack when you check ceiling height and roof penetrations.
Heat, air make-up, mixing rooms and prep stations can be added as one coordinated system.
Because nothing is poured or excavated, installation is usually faster and the permit set is simpler than a pit booth. PFS provides layout drawings and equipment documentation for your fire and building departments and the local air district. Requirements vary by jurisdiction, so confirm with your local authority having jurisdiction.
Factory-direct pricing, ETL-listed construction and support from layout to start-up.
Yes. Airflow is vertical from ceiling to floor in both designs. The only difference is where the exhaust plenum sits: below the slab in a pit, or on top of it in a raised basement.
No. The raised steel plenum sits on your existing slab, which is the main reason shops choose this design.
A drive-on ramp at the entrance brings cars, trucks or carts up to the grated floor level.
It is part of the PFS Zenith downdraft series, ETL listed (Intertek) for the USA and Canada, with a UL 508A control panel and built to NFPA 33.
Yes. Direct-fired or indirect-fired heat packages and air make-up units are available for faster flash and cure times.
Yes. Because it is bolted together on the slab rather than built into it, a raised basement booth can be disassembled and reinstalled at a new location.
