COIN ROKAKI continually innovates, offering outstanding filter cartridges and services, committed to delivering the highest quality and most efficient filtration solutions for you.
HIGH-TEMPERATURE PRIMARY FILTER

HIGH-TEMPERATURE PRIMARY FILTER

Primary filters are designed for the dust filtration in systems, effectively trapping micron-sized and nano-sized particles in high-temperature streams. Filters can be cleaned and reused, providing both environmental benefits and ensuring the proper operation of equipment.
PRIMARY COALESCING FILTER

PRIMARY COALESCING FILTER

The primary function of coalescing filters in air compression systems is to remove impurities, fine oil and gas particles, and odorous gases from the compressed air. In response to the requirements of compressed air applications, factors such as filter pore size, moisture content, residual oil content, etc., are the main criteria for inspection. Airflows that meet quality standards ensure the proper operation of equipment and extension of the life-span of system, which significantly saves the running cost of entire system.
OIL MIST FILTER

OIL MIST FILTER

Developing high-performance filtration technologies for purifying oil, mist, haze, aerosols, and toxic fumes, we have obtained several patents. By integrating specialized industrial processes, we create efficient purification equipment and offer high-efficiency oil-mist separation filters. Applications include: CNC machinery, petrochemical industry, pharmaceuticals, paint spraying and solvent businesses, restaurant kitchens, and more.
PROFESSIONAL EQUIPMENT FUEL FILTER

PROFESSIONAL EQUIPMENT FUEL FILTER

Scope of Application: High-speed railway trains... etc.
PROFESSIONAL DESICCANT FILTER

PROFESSIONAL DESICCANT FILTER

Core technology development of high-performance drying filters, utilizing materials with precise and singular tiny pores, can be used for adsorbing gases or liquids to achieve purification of gases and air purification. Applications: High-speed railway trains, petroleum industry.
OIL-GAS SEPARATOR

OIL-GAS SEPARATOR

Using multiple layers of stacked microfiber filter material to capture oil particles in the oil and gas, the oil particles will coalesce within the filter material layers and drain out to make sure the long life span, while the clean gases will pass through the filter material to achieve oil and gas separation. Applications include: air compressors, high-speed railway trains, etc.
