Perfect for flush-floor hangar installations. Target Keywords: Side-downdraft paint booth, explosion-proof spray booth, Rockwool paint booth, industrial flush floor spray booth, heavy steel coating equipment, VOC filtration plenum.

🚀 Product Overview

The CoatTech KT-PQ-III-PLUS is a specialized industrial spray booth engineered for facilities facing strict height constraints and rigorous fire safety codes. With a highly efficient internal working space of 4700 × 4000 × 3000 mm, this model abandons traditional pit-excavation requirements by utilizing an advanced Side-Downdraft airflow design.

This allows the booth to sit completely flush with your existing factory floor—eliminating dangerous ramps and making the loading of heavy steel fabrications effortless. Built strictly for high-risk industrial environments, it features zero-combustion pure spraying capabilities, making it the premier choice for EPC contractors and metal fabrication hangars across the Middle East and globally.

⚙️ Core Engineering: The Three Pillars of Performance

1. Ventilation & Fan System (Maximum Extraction, Zero Pits)

The ventilation system determines the efficiency of paint mist extraction and the ultimate cleanliness of your working environment.

1.Side-Wall Exhaust Plenum: We have integrated a heavy-duty 1000mm high side-wall exhaust plenum (collection box). This pulls the paint mist horizontally and downwards, providing uniform airflow without requiring a costly civil pit.

2.Flush Floor Compatibility: Because the exhaust is managed through the side walls, your factory floor remains completely flat (no ramps, no steps), allowing forklifts and heavy machinery to roll in safely.

3.High-Volume Airflow: Powered by two 3KW double-inlet centrifugal intake fans and one powerful 7.5KW exhaust fan, delivering a massive 20,000 m³/h airflow to maintain a pristine spraying environment.

2. Filtration System (Quality & Environmental Compliance)

A robust filtration system directly impacts the flawlessness of your coating finish and ensures strict environmental compliance.

4-Stage Eco-Filtration:

1.Intake Pre-filter: EN 779 Class G3 catches large airborne dust.

2.Ceiling Filter: Sub-high efficiency (EN 779 Class F5) full-depth 3D adhesive filter ensures only perfectly clean air hits your workpiece.

3.Fiberglass Paint Stop: Installed directly on the side plenum and exhaust cabinet (EN 779 G3) to trap heavy paint particulates.

4.Active Carbon Granular Filter: Effectively absorbs harmful VOCs, benzene, and xylene from the exhaust gas before it is released into the atmosphere.

3. Fire Safety & Explosion Protection (The Absolute Safety Baseline)

In industrial coating, fire and explosion protection is not an option—it is the bottom line.

1.Class A1 Fire-Rated Enclosure: The entire cabin (walls and roof) is constructed from 75mm and 50mm high-strength Rockwool (Mineral Wool) Panels (120KG/m³ density). These non-combustible panels ensure strict compliance with international civil defense and fire safety codes.

2.IP65 Explosion-Proof Lighting: Equipped with 40 units of dedicated T8 LED tubes housed in fully sealed, IP65-rated explosion-proof light boxes, delivering ≥ 1000 LUX of safe, brilliant illumination.

3.Safe Control Infrastructure: While the main control box is standard, all internal lighting utilizes explosion-proof wiring, flexible conduits, and explosion-proof control boxes.

Specification Details

🛠️ Enhanced Operational Features

1.Mobile Hanging System: Maximize your throughput. The roof is reinforced with a mobile ceiling-mounted rail system capable of supporting up to 100 KG, perfect for efficiently spraying smaller industrial parts and accessories.

2.Integrated Compressed Air Pipeline: Comes standard with a DN20 stainless steel compressed air pipeline featuring quick connectors on both the left and right sides for seamless spray gun operation.

3.Dedicated Maintenance Access: The layout is intelligently designed with a clear maintenance access path, allowing your technicians to inspect electrical systems and replace filters safely and ergonomically.

🏭 Ideal Applications

The KT-PQ-III-PLUS V2 is specifically designed for:

1.Height-Restricted Hangars: Facilities with low overhead clearance (e.g., under fire sprinkler lines).

2.Heavy Metal & Steel Fabrication: Where heavy components require ground-level, forklift-friendly access without ramps.

3.Strict Regulatory Zones: Regions demanding Class-A fire-rated materials and explosion-proof electricals (highly popular in UAE/Middle East industrial zones).

4.Pure Spraying Operations: Facilities that utilize air-dry industrial coatings and do not require integrated thermal baking systems.

❓ Frequently Asked Questions (FAQ)

Q1: Do I need to excavate a foundation pit for this booth?

A: No. The KT-PQ-III-PLUS utilizes a Side-Wall Exhaust Plenum (Side-Downdraft). The booth sits entirely flush on your existing flat concrete floor, saving you massive civil engineering costs and allowing seamless equipment entry.

Q2: Does this booth meet strict Middle Eastern fire safety standards?

A: Absolutely. We replaced standard EPS foam with 120KG/m³ Rockwool insulation, granting the booth a Class A1 fire resistance rating. Combined with IP65 explosion-proof lighting, it is designed to pass rigorous local safety inspections.

Q3: We have a mix of massive steel frames and smaller parts. Can this booth handle both?

A: Yes. Large frames can be rolled directly onto the flush floor, while smaller parts can be suspended from our integrated 100 KG mobile ceiling-mounted hanging system, allowing for highly versatile batch processing.

Q4: How do we connect our spray guns?

A: The booth includes a pre-installed DN20 stainless steel compressed air pipeline with dual quick-connectors (left and right), ready to tie into your factory’s main air supply.
