1. Introduction

The Recirculating Paint Booth is a versatile, completely self-contained spray‐painting enclosure designed for small-scale repair work. Available in 2 × 2 m or 3 × 3 m configurations, it removes volatile organic compounds (VOCs) and recycles clean air in a closed‐loop system—eliminating the need for permanent ductwork or external ventilation installations. Its modular design and lack of side posts under the roof allow easy accommodation of larger workpieces and rapid relocation as your workflow demands.

 Please see the attachments in this arcticle for additonal infomation.

2. Safety Precautions

1. ATEX Compliance: Only use ATEX-certified components (lighting) in potentially explosive atmospheres.
2. Personal Protective Equipment (PPE): Always wear certified respirators, gloves, and protective eyewear when operating the booth.
3. Electrical Safety: Confirm that all electrical connections are made by a qualified electrician and that power is disconnected during installation or maintenance.
4. Fire Safety: Keep a certified fire extinguisher (class B/C) within 5 m of the booth and never store flammable materials inside the enclosure when not in use.

3. Technical Specifications

* Exact height depends on chosen Smartwall configuration and roof modules. smartrepair-shop.com

5. Assembly Instructions

5.1 Site Preparation

1. Floor level: Ensure a flat, stable surface capable of supporting at least 250 kg.
2. Clearance: Maintain a minimum of 1 m clearance around all sides for service access.

5.2 Booth Structure

1. Install Smartwall Rails: Mount vertical rails according to the Smartwall layout (as per SmartWall 3×3 drawings).
2. Attach Side Curtains: Hang the two side curtains on their respective rails. Ensure tensioners keep fabric taut.
3. Fit Front Curtain: Secure the see-through strip curtain at the front opening.
4. Mount Roof Module: Lift the roof frame into place, aligning inlet pipes with the Smartwall rails. Bolt securely.
5. Install LED Lights: Clip ATEX LED fixtures to designated mounting points on the roof frame. Wire to the lighting circuit.

5.4 Final Checks

• Verify all bolts and clamps are tightened per torque specifications.
• Confirm electrical connections are secure and properly earthed.
• Power up fans and monitor differential pressure; adjust fan speed until recommended airflow (0.3 m/s) is reached.
• Test LED lighting and ensure full illumination.

6. Operating Instructions

1. Start-Up:
• Switch on the monitoring system; verify all sensor readings are within normal range (zero differential pressure, <0.1 mg/m³ VOC).
• Activate fans and lighting via the control panel.
2. Spray Operation:
• Work at least 150 mm inside the booth opening to ensure proper containment.
• Monitor VOC and pressure alarms.
3. Shutdown:
• Turn off spray equipment first, then lighting, and finally fans.
• Allow the booth to run for 5 minutes post-painting to clear residual overspray.

7. Maintenance

• Daily: Inspect curtains for tears; wipe down interior surfaces.
• Weekly: Check differential-pressure gauge; replace paint-stop inlet filters if ΔP > 100 Pa.
• Monthly: Visually inspect activated carbon cartridges; look for signs of saturation or odor breakthrough.
• Biannual: Replace all filters (activated carbon and paint-stop) or sooner if pressure drop exceeds 200 Pa.
• Annual: Calibrate sensors and verify ATEX certification labels.
