Koganei Air Preparation and Treatment Products
Help your pneumatic equipment receive the air it needs to operate consistently. Koganei offers components for filtering compressed air, regulating pressure, managing collected water, drying air, and monitoring the air supply.
Moisture, contaminants, or unstable pressure can affect valves, cylinders, and other downstream equipment. Start with the condition you need to address, then select components that meet the required flow, pressure, filtration, and installation specifications.
