Professional Compressed-Air Application Equipment
NHOU® Professional Spray Gun with Internal Cup – Viscous Coatings
A durable compressed-air spray gun engineered for controlled application of viscous rustproofing materials, underbody coatings, wax inhibitors and compatible water-based paints.
The NHOU® Professional Spray Gun is designed for applying thick and highly viscous materials that require consistent product flow, controlled atomisation and reliable compressed-air operation.
Its internal pressurised feed cup supports the application of underbody coatings, rustproofing waxes, corrosion-protection products and compatible specialty finishes. Adjustable spray controls allow the user to adapt the spray diameter and jet length to the material and treated surface.
Key Benefits
Designed for Viscous Materials
Suitable for thick rustproofing products, underbody coatings, wax inhibitors and compatible water-based paints.
Internal Feed Cup
The integrated pressurised container helps maintain consistent flow when applying heavier coating materials.
Adjustable Spray Pattern
Spray diameter and jet extension can be adjusted to suit different materials, surfaces and application tasks.
Low Air Consumption
Designed for efficient operation with a suitable compressed-air supply, including appropriately sized smaller workshop compressors.
Durable Construction
Features a nickel-plated aluminium body, anodised aluminium cup and stainless-steel needle and nozzle components.
Serviceable Modular Design
The removable suction pipe simplifies cleaning, while optional kits may support alternative application configurations.

Recommended Applications
This spray gun is suitable for professional and advanced DIY applications requiring controlled delivery of thicker coating materials.
- Vehicle underbody coatings
- Rustproofing waxes and oils
- Wheel-arch protection
- Chassis and frame coatings
- Corrosion-prevention compounds
- Compatible water-based paints
- Industrial maintenance coatings
- Woodworking finishes
- Specialty workshop applications
- Professional restoration projects
Internal Pressurised Feed System
The integrated feed cup is designed to support the movement of viscous materials toward the nozzle. This helps maintain a more consistent flow than a conventional gravity-only system when applying suitable thick coatings.
- Integrated anodised aluminium feed cup
- Suitable for compatible thick coating materials
- Adjustable material and spray delivery
- Detachable suction pipe for easier cleaning
- Professional compressed-air connection required
Precision and Control
Adjustable controls allow the operator to adapt the spray pattern to the material viscosity, coating thickness and size of the treated area. Correct adjustment reduces unnecessary overspray and supports more consistent coverage.
Compressor note: Motor power alone does not confirm compressor compatibility. The compressor must provide the required operating pressure, airflow and duty cycle for the selected material and spray settings.

Setup and Application Guide
- Read the instructions: Review the spray-gun manual and coating manufacturer’s directions before assembly or use.
- Confirm material compatibility: Verify that the selected coating is suitable for the gun, cup, seals, needle and nozzle.
- Prepare the material: Mix or condition the coating according to the manufacturer’s instructions.
- Fill the cup: Add an appropriate quantity without exceeding the permitted fill level.
- Connect the air supply: Attach a suitable regulated compressor and confirm that all connections are secure.
- Set the pressure: Begin at the lowest suitable setting and adjust within the specified operating range.
- Test the spray: Use a test panel to adjust material flow, spray diameter and jet extension before treating the final surface.
- Apply evenly: Maintain a consistent distance and use smooth, overlapping passes.
- Depressurise safely: Disconnect and release stored pressure according to the equipment instructions.
- Clean immediately: Disassemble and clean all material-contact components using a cleaner approved for the coating.
Material compatibility note: Do not use aggressive solvents, reactive chemicals or unsupported materials that may damage the cup, seals, valve, needle or nozzle. Always follow the coating and equipment manufacturers’ instructions.
Frequently Asked Questions
What materials is the spray gun designed for?
It is designed for compatible viscous coatings, underbody products, rustproofing waxes and selected water-based paints.
Does the spray gun include an internal container?
Yes. It includes an anodised aluminium internal feed cup designed to support the application of suitable viscous materials.
Is an air compressor included?
No. A compatible regulated air compressor, hose and connectors are required separately.
Can the gun work with a small compressor?
It is designed for relatively low air consumption, but compressor suitability depends on available airflow, operating pressure, tank capacity and duty cycle rather than motor power alone.
What is the recommended operating pressure?
The specified operating range is 0.5–3.5 bar. Begin at a lower pressure and adjust according to the material and required spray pattern.
Can the spray pattern be adjusted?
Yes. The gun provides adjustment of the spray diameter and jet extension for different coating tasks.
Is it suitable for NHOU® rustproofing products?
It is intended for compatible NHOU® and similar viscous corrosion-protection materials. Confirm product compatibility and required nozzle configuration before use.
Is the suction pipe removable?
Yes. The suction pipe can be detached to simplify cleaning and maintenance.
How should the gun be cleaned?
Depressurise the system, empty the cup and clean all material-contact parts immediately using a cleaner approved for the applied coating.
Safety Information
Read the instruction manual and coating Safety Data Sheet before use. Wear suitable eye protection, gloves, protective clothing and respiratory protection where required. Never exceed the maximum pressure, never point the gun toward people or animals, and always depressurise the system before cleaning, adjustment or maintenance.
