Powder Accessories & Spare Parts
Accessories and spare parts for manual powder coating keep systems available and surfaces reproducible. We supply nozzles, electrodes, gun & control parts, injectors or powder pumps, powder and air hoses, quick couplings, filter cartridges, sieving units, grounding accessories as well as suspension and masking – designed precisely to the powder system, geometry and throughput.
Applications & benefits
Suitable for manual systems and manual booths in small series, repair and frequent color changes. Correctly selected components ensure a stable powder flow, constant charging and uniform film thicknesses. They reduce downtime and material losses and enable planned maintenance.
Technology & settings
- Nozzles & electrodes: choose shape and diameter to suit edges, internal areas and flat sections; clean electrodes regularly.
- Powder delivery: set injector or pump for a stable volume flow; adapt hose lengths and inner diameters (ID) to the geometry.
- Filters & sieving: sufficient filter area and regular sieving ensure consistent powder quality.
- Air quality: use dry, clean compressed air; adjust kV and µA to the respective recipe profiles.
- Safety: comply with ATEX and ensure reliable grounding (<1 MΩ) for safe processes.
Accessories & integration
The range includes nozzles and electrodes, gun bodies and triggers, injectors, powder pumps, powder and air hoses, push-in and threaded couplings, filter cartridges, sieving units, grounding clamps, suspension and masking, cables and connectors as well as maintenance and sealing kits.
We check compatibility (e.g. gun model, port pattern) and handle the integration into manual system and booth.
Key benefits at a glance
- Consistent quality – precisely fitting nozzles, clean electrodes, stable delivery
- Less downtime – planned maintenance with original/matching parts
- Efficient – low powder consumption, reduced rework

Learn moreFrequently asked questions about accessories & spare parts
Which accessories and spare parts are important for powder coating?
Core parts are nozzles and electrodes, gun and control components, powder injectors and pumps, powder and air hoses, quick couplings, filter cartridges, sieving units, grounding accessories, suspension/masking as well as cables and connectors. They ensure constant powder flow, stable charging and reproducible film thicknesses.
How do I select suitable nozzles, hoses and filters?
Selection depends on part geometry, powder system (EP/PES/hybrid), desired film thickness, air volume flow and color change frequency. Important are nozzle shape/diameter, suitable electrodes, antistatic or food-grade hoses, correct hose lengths as well as sufficient filter area and appropriate filter class.
What improves process stability, safety and quality?
Regular replacement of wear parts, constant grounding (<1 MΩ), dry and clean compressed air as well as correctly set kV/µA increase process safety. Sieving, tight plug connections, short dead volumes, ATEX-compliant components and documented maintenance intervals improve finish and reproducibility.
