Manual powder booths
Manual powder booths for manual powder coating combine extraction, filtration technology, optimized airflow and lighting into a compact, ergonomic work cell. We precisely design booth size, air volume flow (m³/h), filter area/class, recovery/screening as well as grounding & ATEX to match part geometry, powder system and throughput.
Applications & benefits
Ideal for small batches, maintenance, sample parts and frequent color changes. Properly designed manual booths provide clean air, homogeneous airflow and low overspray – the basis for reproducible film thicknesses, less rework and high first-pass transfer efficiency.
Technology & settings
Airflow: uniform supply and extraction air prevents turbulence; align flow with the part and the gun. Filters: sufficient filter area and suitable filter class ensure constant negative pressure; screening keeps powder quality stable. Lighting: bright, low-shadow LED lighting for quality inspection. Safety: grounding, ATEX, certified pressure relief (PRV) and tight hose connections. Acoustics/ergonomics: noise control and well-thought-out access points reduce operator fatigue.
Accessories & integration
Booths with filter modules, supply/exhaust air packages, LED lighting, powder recovery, screening units, hangers/masking, compressed air treatment, grounding clamps and maintenance & sealing kits. We handle the compatibility check (parts, air performance, connection pattern) and integration into workshop and line.

What is a manual powder booth and what is it used for?
Manual powder booths are powder coating booths with integrated extraction and filtration for manual application. They keep the workplace clean, minimize overspray and enable flexible small batches, sample parts and frequent color changes.
How do I select air volume flow, filters and booth size?
The design is based on part dimensions, desired film thickness, powder type and throughput. Important factors are sufficient air volume flow (m³/h) with uniform airflow, suitable filter area and filter class, as well as ergonomic accessibility and good LED lighting.
What increases stability, safety and surface quality?
Constant grounding (<1 MΩ), dry, clean compressed air, correctly set gun parameters (kV/µA) and a flow-optimized booth improve the finish. ATEX-compliant components, regular filter screening/replacement, tight hose connections and low dead volumes increase process safety and reproducibility.
