FP32 1/4", 33 3/8", 34 1/2" Preparation
To achieve peak performance and strict compliance with industry benchmarks, the assembly of calibration components requires meticulous precision. Every component must be installed in strict accordance with the maximum flow requirements defined by the system design, ensuring seamless operation and efficiency.
Before installation, thorough cleaning of all ports and fittings is essential. Use suitable solvents or compressed air to remove any particulate matter completely, preventing dust from entering the air path. This preventive measure not only boosts operational efficiency but also prolongs the lifespan of downstream equipment.
Moreover, close attention should be paid to the proper alignment of air flow, which must be carefully verified against the clearly marked arrow indicators on the product. At the same time, ensure that all port and thread sizes match the specified system requirements precisely to avoid leaks and operational malfunctions. Following these procedures rigorously guarantees smooth integration and reliable long - term performance.

Activate the manual drain valve by smoothly rotating the user - friendly lever to the "↓" position, which immediately starts the continuous release of exhaust and water from the filter cup. This crucial step must be carried out as soon as the water level reaches the designated maximum mark, ensuring consistent dehumidification performance. Delaying drainage can lead to moisture accumulation, potentially damaging connected equipment. To halt the process, simply align the lever with the "↑" indicator; this seals the valve and prevents any pressurized leaks. Regularly follow the maintenance schedule to avoid blockages and maintain the valve's optimal functionality.


The NANPU Zinc Alloy Air Drying System enjoys a vast application market. In the automotive manufacturing sector, it ensures clean air for paint - spraying processes, preventing particle - induced blemishes on car surfaces. Electronics production lines rely on it to safeguard sensitive components from moisture and airborne particles during assembly. In the food and beverage industry, it maintains a dry and contaminant - free air supply for packaging equipment. Even in the aerospace industry, where precision is crucial, this system plays a role in maintaining optimal conditions for various pneumatic tools and equipment. Its superior air - purification capabilities make it a preferred choice across these diverse sectors.
