Product Features
Dual Pressure Gauges, Monitoring Both Inlet and Outlet Pressure：
Displays the inlet air pressure and outlet working pressure simultaneously, allowing real-time monitoring of whether the air compressor is providing sufficient air supply. This prevents unstable dry ice output caused by insufficient air supply, making operation safer and more controllable while reducing the risk of damage to the engine caused by improper operation.
Lower Air Compressor Requirements, Ideal for Small and Medium-Sized Repair Shops：
A minimum air pressure of 4 bar is sufficient for normal operation, requiring only a 1-2 m³/min air compressor. Compared with the HTS818, the air flow requirement is reduced, allowing the machine to operate with a standard workshop air compressor without the need to replace it with a higher-power model, reducing equipment investment costs.
Large-Flow Oil-Water Separation System, Reduces Dry Ice Blockage：
Equipped with an upgraded large-flow oil-water separator that efficiently filters moisture from compressed air, preventing moisture from entering the hopper and causing dry ice to absorb water, clump, or block the pipelines. It improves stability during continuous operation and reduces downtime caused by blockages.
Spiral Anti-Clumping Dry Ice Feeding System, Continuous and Stable Dry Ice Output：
The spiral stirring and dry ice feeding mechanism prevents dry ice from bridging and clumping, while the blasting flow rate can be continuously adjusted. Use lower pressure for cleaning intake valves and precision components around sensors, and higher pressure for removing heavy carbon deposits. The flexible physical cleaning process does not damage aluminum alloy pistons or valves and eliminates the risk of cylinder scratches caused by residual walnut shell abrasives.
Large 7.5kg Hopper, Supports Continuous Cleaning of Multiple Vehicles：
A full hopper of dry ice can support continuous operation on multiple vehicles, reducing the need for frequent refilling and improving service bay efficiency. Carbon cleaning on a four-cylinder engine can be completed in approximately 15 minutes without disassembly, eliminating the need to remove the cylinder head.
Residue-Free Physical Cleaning, Eco-Friendly and Safe for Catalytic Converters and Oxygen Sensors：
The dry ice sublimates directly into carbon dioxide gas upon impact, leaving no wastewater or blasting media residue. No chemical agents are used, preventing corrosion of the catalytic converter and oxygen sensors. After cleaning, only the removed carbon dust and debris need to be cleaned up.
Industrial Metal Housing, Comprehensive Safety Features：
The reinforced metal housing is durable and designed to withstand demanding automotive repair environments. Equipped with an emergency stop button, spray gun holder, and universal casters with a push-pull design for convenient mobility. Multiple spray nozzle accessories are included as standard to meet different cleaning requirements for combustion chambers and engine bays.
