Problem-Scenario-Solution (FAQ)

Frequently Asked Questions & Custom Engineering Solutions

Q1: Our workshop is narrow, and side placement of the air cabinet is impossible. How can we fit a 10-meter spray booth?
Solution: The CoatTech CT-PQ-III-PLUS features an engineered Rear-Mounted Cabinet design. By repositioning the intake/exhaust air generator and heating units to the back of the booth, we eliminate lateral width constraints, allowing you to maximize available workshop length without compromising airflow efficiency or technician workspace.

Q2: Can this spray booth handle lifted 4x4 off-road SUVs, double-cab pickup trucks, or high-roof commercial vans?
Solution: Yes. Standard spray booths often lack the vertical clearance needed for modified vehicles. The CT-PQ-III-PLUS is built with an increased internal height of 4.5 meters (15 ft) and a generous 4.0m × 4.1m main door entrance, providing seamless drive-in access and ample working clearance for elevated vehicles and oversized equipment.

Q3: What if we cannot excavate a pit in our rental facility or existing concrete floor?
Solution: This model includes a fully self-supported 400mm Raised Metal Basement Structure. It eliminates the need for expensive civil pit excavation. Equipped with 4 heavy-duty steel ramps (750 × 2500 × 400mm), vehicles can easily drive up onto the platform while maintaining full underbody airflow and overspray extraction.

Q4: Is the floor grating strong enough to support heavy modified SUVs or commercial pickups without sagging?
Solution: Absolutely. The basement foundation is reinforced with square tube framing and high-tensile 40×4mm flat iron welded twisted steel grating, delivering a heavy-duty axle load capacity exceeding 3.2 tons. It comfortably supports heavy 4WD chassis and utility vehicles.

Q5: How does this system meet strict local environmental and paint finish quality standards?
Solution: The booth incorporates a 4-Stage Filtration & Air Purification System:
G3 Primary Pocket Filters for intake air pre-filtration.
F5 Full-Depth Adhesive Ceiling Filters ensuring dust-free down-draft airflow.
Dual-Layer Fiberglass Paint-Stop Mats (on basement & exhaust cabinet base) for overspray capture.
Activated Carbon Granule Filters for effective VOC (benzene/xylene) odor adsorption and emission compliance.
