Product Lines & Key Models
Wonder‑Gun Series
The Wonder-Gun is a high-performance air tool that can perform blowing, suction (vacuum), transfer, and dust recovery using compressed air. It is capable of handling abrasives (e.g. glass beads, aluminum oxide, steel grit) or liquids (e.g. oil) and is used for surface cleaning, paint removal, rust & scale removal.
-
Model Example: W301‑ES‑22‑TH — an air blast type that removes rust, scale, and paint from parts and small equipment, preparing them for further finishing.
Silent Cleaner Series
Silent Cleaners are vacuum / dust-collecting tools that operate quietly (exhaust sound kept low), used to gather chips, sawdust, slurries, metal debris, etc. They incorporate jet ejector mechanisms for suction and use filters to prevent dust recirculation.
Mini‑Porter Cyclone
This is a cyclone separator device that effectively separates airborne powder or dust from the air stream using centrifugal force. It is designed to work continuously without clogging and is often used in conjunction with the Wonder-Gun or vacuum systems.
Technical Features & Strengths
-
Multifunctional Pneumatic Tools: Devices combine blowing, suction, material transfer, and recovery in one unit (e.g. Wonder-Gun)
-
No Moving Parts Inside: The design avoids internal rotating components, reducing maintenance and breakdowns
-
Low Noise & Safe Operation: Silent Cleaners keep exhaust noise under 60 dB; safety valves protect against pressure spikes
-
High Efficiency in Dust / Chip Handling: Mini-Porter Cyclone separates particulates almost completely; recommended in scenarios where dust clogging is problematic
-
Modular & Set Configurations: Devices are provided in set kits combining air guns, hoses, collectors, and filters
Applications / Use Cases
-
Cleaning and surface preparation of metal parts (removing rust, scale, paint)
-
Collecting chips, metal shavings, sawdust, sludge, etc.
-
Handling powders and dust in manufacturing or laboratory environments
-
Vacuum suction and dust collection systems in processing plants
-
Use in industries such as machining, casting, mold making, electronics, and maintenance
