Batch Powder Coating Booth
Open-Face Design. Three-Stage Filtration.
Batch Powder Coating Booths are purpose-built for low-to-mid volume powder coating operations where shop space efficiency and consistent air quality are non-negotiable. The open-face, open-front design allows operators to load large or small parts without obstruction, while the booth’s tubeaxial exhaust fan draws air continuously through the working area and into the rear exhaust plenum. Standard interior widths run from 4 to 16 feet with 7 and 10-foot height options, covering airflow ranges from 2,800 CFM up to 12,000 CFM to match the scale of your finishing line.
The filtration system at the core of every RTT batch powder booth is a three-stage design engineered to capture airborne powder dust before it re-enters the facility. Stage 1 uses a blanket-style filter to capture coarse overspray; Stage 2 deploys a bag-style filter for finer particulate; Stage 3 employs a HEPA-type filter for final cleanup. All filtered air discharges back into the room – eliminating the need for make-up air and reducing HVAC complexity. A Final Filter Proving Assembly interlocks with the air solenoid valve to confirm filters are installed and functional before the gun fires, protecting both equipment and finish quality.
Every RTT batch powder coating spray booth ships with 18-gauge prime-quality galvanized steel panels and support members that are laser-cut and precision-formed for bolt-together assembly in the field. ETL-listed E-Light LED fixtures — available in 4,000 and 8,000 lumen models — provide code-compliant illumination rated Class 1 Division 2 (Groups A, B, C, D) and Class 2 Division 2 (Groups F and G). RTT batch powder booths meet and exceed all applicable OSHA and NFPA regulations, and optional UL-listed control panels are available to bring the complete system into a single certified package.

Benefits
- Reduce powder dust contamination in your facility — filtered air discharges back into the room, keeping the shop environment clean without external exhaust ducting.
- Lower installation cost and lead time — bolt-together, laser-cut panels with consistent fit reduce field labor and eliminate custom fabrication.
- Protect finish quality automatically — the Final Filter Proving Assembly interlocks the gun’s air solenoid with the exhaust fan, preventing application before airflow and filtration are confirmed.
- Scale the booth to your production without a facility redesign — 21 standard configurations from 4′×7′×5′ to 16′×10′×7′ accommodate parts of virtually any size within a low-volume batch workflow.
- Reduce operating energy costs — optional VFD fan control lets you match fan speed to actual load, reducing amp draw during lighter production runs.
- Maintain code compliance without custom engineering — every booth meets OSHA and NFPA regulations out of the box, with optional ETL-listed control panels available.
- Cut lighting maintenance and interlock costs — ETL-listed E-Light LED fixtures do not require a safety interlock, eliminating that component and its associated maintenance.

Bright, Efficient Lighting – Included
Each booth includes E-Light LED lighting, offering:
- Lower energy consumption
- True color rendering
- Extended life and reduced maintenance costs
LED housings are constructed of 22-gauge steel and powder-coated white. E-Lights are ETL listed for U.S. and Canada, rated Class 1 Division 2 (Groups A–D) and Class 2 Division 2 (Groups F & G).
RTT lighting is calculated and engineered using photometric software. E-Light fixtures are ETL listed and designed for proper use in spray booths. Because of this, our E-Light does not require a safety interlock saving on installation cost and additional maintenance.

Frequently Asked Questions
How Do I Adjust Airflow on My Powder Collector?
The control panel is equipped with a “Fan Speed” knob on the door. Adjust the knob to a higher value for more airflow, or a lower value for less airflow.
Where Should the Temperature Sensor Be Located on My Spray Booth?
RTT recommends that the temperature probe be in the discharge ductwork of the Air Make-up Unit (AMU). The probe is to be located as far from the discharge location of the AMU as possible before entering the paint booth intake plenum. This configuration helps to avoid sharp spikes in temperature and will even out the ramp and soak time of the burner. Eliminating the possibility of an over-temperature situation inside the AMU. In rare instances, the temperature probe may be in the intake plenum of the spray booth. Please consult with RTT Technical Support before locating the temperature probe anywhere other than the AMU discharge ductwork.
Why Are My Spray Booth Doors Being Blown Open?
This is typically caused by excessive incoming gas pressure affecting system balance. When gas pressure exceeds regulator ratings:
• Airflow and burner output become unstable
• The system may create positive pressure inside the booth
• Doors can blow open due to improper pressure differential
Check the valve train regulator, system gas pressure, and follow the manufacturer’s recommended pressure ranges.
My Spray Booth and Oven Controls Require a Password to Change Settings - What Is It?
CT/CTC AMU – All passcodes provided in the RTT Booth & AMU Detailed Start-up Guide).
Operator passcode is 2050
Oven – All passcodes in the Oven Operation & Maintenance manual. Maintenance passcode is 1111
My Exhaust Fan Is Not Running Even Though My Booth Has Power — What Could Be Causing It?
There could be several issues that could cause your exhaust fan not to operate. If you have confirmed you have power, do you have a fault on your Variable Frequency Drive (VFD)? Check to see if there is a fault code displayed on the VFD. Depending on the make and model of your VFD these codes can differ.
