NA-G20 Natural Gas Automotive Paint Booth – Full-Size Car Spray Booth | CE, FCC certified

The NA-G20 paint booth measures 7000 × 5100 × 3300 mm outside and 6900 × 3900 × 2650 mm inside, giving enough space for most sedans, coupes, hatchbacks, SUVs and light trucks while still leaving room to move around the vehicle.

• Outside size: 7000 × 5100 × 3300 mm (approx. 23.0' × 16.7' × 10.8').
• Inside working size: 6900 × 3900 × 2650 mm (approx. 22.6' × 12.8' × 8.7').

For many buyers, this matches what they expect from a standard full-size automotive spray booth footprint.

The NA-G20 uses a natural-gas burner (FS10-type) as the primary heat source. With around 100,000 kcal/h of reference heating capacity, it is designed to take the booth from near room temperature up to typical refinish bake temperatures under factory reference conditions, similar to other natural gas–fired downdraft booths on the market.

• Heating type: natural-gas burner (no on-booth diesel burner and no electric infrared package).
• Approximate burner capacity: about 100,000 kcal/h (factory reference, natural gas).
• Supports forced drying of primer and clear coat with gas-fired heat.

This suits shops that prefer traditional gas heating, aiming for stable bake cycles and lower electrical draw compared with fully electric-heated systems.

The NA-G20 is a downdraft automotive spray booth: air comes from the plenum above and is drawn down through the floor grilles to move overspray away from the painter and the vehicle, a pattern commonly used in high-quality refinish booths to improve finish consistency and overspray control.

• Downdraft pattern: air is delivered from above and pulled down through the floor grilles.
• Supply fans: 2 × 3 kW dual fans on the intake side.
• Exhaust fan: 1 × 5.5 kW centrifugal exhaust fan included in the standard package.
• Ductwork: 2 straight ducts plus 90° and 45° elbows to connect into your exhaust stack or treatment system.

Having both dedicated supply and exhaust fans helps maintain balanced airflow and booth pressure for repeatable spray and bake cycles throughout the day.

The NA-G20 combines top, vent and floor filtration to help control dust and overspray in the automotive paint booth.

• Top filtration in the ceiling area above the booth.
• Vent filtration on incoming make-up air.
• Bottom filtration beneath the floor grilles.

With regular filter maintenance, this multi-stage chain is intended to support clean refinish work and reduce rework due to dirt in the clear coat.

The NA-G20 cabin uses insulated steel wall panels, a galvanized roof and a raised steel base with grilles and plates to feel like a permanent, professional installation.

• 50 mm EPS wall panels with 0.37 mm color-steel facing for insulation and rigidity.
• 0.8 mm galvanized roof plate.
• Approx. 370 mm plenum / purification layer above the booth ceiling.
• 2 floor grilles + 3 patterned plates on a 280 mm high galvanized base, with climbing platform around 750 × 1800 mm.
• Main door: bordered wall-panel doors, 3000 × 2600 mm.
• Personnel door: 750 × 1900 mm, matching the booth wall color.
• Equipment box / air unit can be mounted on the right, left or rear side to suit your building.

When inspectors, insurers or fleet customers walk into the spray area, the booth presents as a serious long-term asset rather than a temporary box.

The NA-G20 is a gas-heated industrial spray booth designed to run on three-phase power for fans and controls, with exact voltage and frequency set per order and region. Burner fuel is supplied by your natural gas service.

• Total installed electrical power: approx. 12 kW (fans, controls and auxiliaries).
• Gas-fired heat from an FS10-type burner, using natural gas as the fuel.
• Designed for industrial three-phase power (exact voltage and frequency configured per order and region).
• For the US and other markets, local electrical and mechanical engineers adapt the booth to the available three-phase supply, gas service and safety devices to meet local code.

Final approval always depends on local building codes, fire regulations and environmental rules in your area.

The NA-G20 is aimed at body shop owners comparing full-size automotive spray booths for everyday collision and refinish work who want both strong downdraft airflow and a natural-gas-fired heating system.

Typical questions from buyers include:

• “What is the best full-size automotive spray booth with a gas-fired burner for my body shop?”
• “Do I need both supply and exhaust fans in the base package?”
• “Is a natural gas automotive spray booth enough to bake clear coat fast?”

Typical buyers:

• Collision and refinish shops that need to control cycle time and key-to-key.
• Growing body shops planning a 10–15 year infrastructure upgrade, not a temporary fix.
• Owners who care about image with inspectors, insurers, DRP partners and painters.
• Shops that prefer gas heating, downdraft airflow and integrated exhaust in the base booth package.

Is this a good automotive spray booth for a small to medium body shop?

Yes. The NA-G20 footprint and performance are tuned for daily collision workloads on cars, SUVs and light trucks. If you are searching for a “full-size downdraft automotive spray paint booth with a natural gas burner”, this model fits that use case.

Does this booth work with waterborne paint systems?

Yes. Airflow, heating and filtration are suitable for modern solvent-borne and waterborne refinish systems when installed and operated according to your paint manufacturer’s guidelines.

Can I install this car spray booth in the United States or other countries?

The booth is designed to be adaptable to different power systems, gas services and regulations, including US and other markets. Final approval always depends on local building departments, fire marshals and environmental agencies in your region.

Are the specifications fixed?

No. The NA-G20 platform is continuously updated. Dimensions, components and configuration may change over time or be customized. Always rely on your signed drawings, quotation and installation package for exact, current specs.
