Key Features
HTS559 is professional walnut shell blasting equipment built around spray-and-recovery cleaning, media and residue management, intake carbon removal, adapter coverage, external-air blasting, 0.6–1.2 mm walnut abrasive support, workshop mobility, and warranty support.
5 Intake Adapters For Different Port Shapes
Equipped with 5 adapter types for different intake-port shapes and cleaning setups. Match the adapter to the specific engine and intake-port shape before cleaning. The included adapter set fits multiple intake-port shapes, but it is not universal for every engine.
Integrated Spray And Vacuum Recovery
HTS559 uses walnut blasting for carbon cleaning while integrated vacuum recovery collects loosened residue and spent media, helping reduce manual cleanup.
Built-In Dust Filter For Collected Media And Residue
The built-in dust filter helps manage collected walnut abrasive and carbon residue during simultaneous spray-and-recovery operation. The collection and filtration system supports abrasive recovery. Reuse recovered abrasive only when the service procedure for the specific vehicle permits it and the media remains suitable for reuse.
Deep Intake Carbon Deposit Removal
Designed to remove sticky carbon deposits from the intake pipe, intake manifold, and the backs of the intake valves. Any changes in idle quality, combustion behavior, air-fuel ratio, power, or fuel economy depend on the vehicle condition and diagnosis.
External Air-Driven Blasting + 1400W Vacuum Recovery
The 1400W rated-power machine supports vacuum recovery, while an external air compressor supplies the blasting force for walnut-shell cleaning. The external compressor must provide suitable airflow and dry air for the cleaning procedure.
Walnut Shell Abrasive Cleaning
HTS559 uses 0.6–1.2 mm walnut-shell abrasive as the cleaning media. Use dry, compatible walnut-shell media, follow the supplier Safety Data Sheet (SDS), and wear appropriate personal protective equipment (PPE). Walnut-shell media can create dust and may present allergen concerns.
360° Swivel Casters
360° swivel casters make the machine easier to move around the workshop.
Walnut Media Recovery & Reuse
The recovery and filtration system helps separate collected walnut-shell abrasive from carbon residue so suitable media can be reused.

From Setup to Final Vehicle Check
Step-by-Step Workflow
HTS559 works with 0.6–1.2 mm walnut abrasive, external compressed air, and vacuum recovery. The sequence below covers media setup, valve-position confirmation, anti-clog airflow, port-by-port cleaning, residual-media recovery, reassembly, leak checks, diagnostic scanning, and a final vehicle check.
01
Step 1
Connect Hoses And Nozzle
Secure all hose and nozzle connections before media is loaded so the blasting and recovery path is ready.
- Connect the recovery hose securely.
- Connect the blasting gun, nozzle, and related fittings.
02
Step 2
Select And Seal The Adapter
A correctly matched, sealed adapter helps keep blasting and recovery focused on the target intake port.
- Choose the adapter that matches the intake-port shape.
- Confirm a secure seal before blasting.
- Remember that the five supplied adapter types are not universal for every engine.
03
Step 3
Position The Nozzle In The Recovery Path
Position the nozzle inside the suction path so blasting and vacuum recovery work together.
- Insert the nozzle tube into the suction-hose opening.
- Keep the nozzle within the recovery path.
04
Step 4
Load Walnut Abrasive
Load the model-specific amount of compatible abrasive before starting, and follow the HTS559 loading procedure supplied with the machine.
