Walnut Blasting With Simultaneous Recovery and HEPA Filtration
The HTS728 blasts fine walnut-shell media with compressed air while recovering media and carbon residue through HEPA and dust filtration. It cleans intake ports and valves, and the combustion chamber through the spark-plug hole where the vehicle service procedure supports it. An external compressor is required and not included.
- Projection + récupération simultanées
- Filtration HEPA
- Modes récupération / remplissage
- Abrasif de 0.4–0.6 mm
- Compatible avec les chambres de combustion
Key Features
-
Récupération et filtration intégrées
The machine sprays and recovers at the same time; a filter cartridge and screen separate carbon from walnut media so suitable media can be reused.
-
Modes récupération et remplissage
Dedicated switches for recovery and media filling, with power and filling indicator lights on the control panel.
-
Poignée de buse à deux modes
Switch between blasting mode for carbon removal and air-only mode for clearing residual media and deposits.
-
Régulation de pression
A pressure gauge and regulating knob let you monitor and set blasting pressure per the manual.
-
Intake, Valve and Combustion-Chamber Cleaning
Work port by port across intake manifolds and intake valves; combustion-chamber, exhaust-valve or other extended-area cleaning only where the vehicle procedure supports it.
-
Mobilité dans l’atelier
Handle and 360° swivel casters move the unit between bays.
Highlights
Control Panel
Mode switches, indicator lights, pressure knob and gauge in one row.
Nozzle Handle
Blasting and air-only buttons on the handle.
Filtration et réutilisation
Built-in filter cartridge and screen separate carbon from recovered media.
Avant et après
Results depend on the engine and the cleaning area its service procedure supports.

How to Use
- Installez la machineConnect the recovery hose and elbow, the blasting tube or nozzle, the external air supply and AC power.
- Chargez l’abrasif de noixSet Recovery off and Filling on, add compatible media within the load limit, then switch Filling off and build pressure.
- Préparez le véhiculeRemove spark plugs or the intake manifold as the procedure requires, close the target valves and seal the other ports.
- Nettoyez les conduits d’admissionMake a sealed recovery connection, switch Recovery on, set nozzle depth and pressure, and clean each port in sequence.
- Nettoyer la chambre de combustionOnly where supported: work through the spark-plug hole with valves closed and recover media throughout.
- Clear residueStop media and air, complete final vacuum recovery and inspect with good lighting or a borescope.
- Remonter et vérifierRefit parts, then complete leak checks, diagnostic scanning and idle checks.

Good to Know
Attention
- Requires an external compressor supplying dry, filtered air; check that the tank, hose, fittings and duty cycle support the required airflow.
- Never blast with the target valve open, and do not clean an area just because the nozzle can reach it.
- The adapters and nozzles fit multiple port shapes but are not universal; confirm fit and seal on each engine.
- Remove all visible residual media before starting the engine rather than relying on it to burn away.
- Walnut-shell dust may trigger allergies; wear goggles and respiratory protection, ventilate the area and follow the media supplier’s SDS.
Entretien
- Keep media dry and replace it if it becomes contaminated or clumped or cleaning performance drops.
- Decide when to clean through inspection and diagnosis, not a fixed mileage interval.
