FRPD-F44/FRPD-F46/FRPD-F46/FRPD-F46D
NANPU 1/2" 3/4" NPT Industrial Grade 4 Stage Air Drying System - Particulate Filter, Coalescing Filter, Desiccant Dryer & Air Regulator, Metal Bowl, Auto Drain, Suitable for Paint Spray＆ Plasma Cutter
High Pressure Endurance: Operates optimally under a pressure scope of 30-175 psi; Flow Capacity: 141 CFM (4000 L/min) Elevated Safety Standard: A premium metal bowl integrated with a visible sight glass at each stage guarantees safeguarding for both operators and the system during the entire procedure.
Stage 1: Filtration & Regulation Unit: The compressed air water separator filter is furnished with a 5-micron element, featuring outstanding filtration efficacy, prolonged service duration, and reusability. It eliminates the majority of moisture and particles in the air pipeline; the pressure regulator accurately adjusts and stabilizes air pressure.
Stage 2: Coalescing Filtration Device: Fitted with a 0.01-micron element, this filter removes 99.9% of moisture, fine particles, and oil that traverse the Stage 1 combination unit. A red indicator will project when the filter element needs replacement.
Stage 3: Desiccant Air Drying Unit: This dryer thoroughly dehumidifies and purifies air before it enters pneumatic tools. Desiccant beads must be added to the metal bowl, and they will shift from blue to pink when replacement is required.

NANPU Preparation and Pressure Adjustment
1.All calibration modules must meet peak flow specifications.
Before fitting, ports and connectors should be cleared to efficiently block dust entry into the air path.
Confirm alignment between airflow orientation and the directional arrow on the product casing, and check conformity of port and thread sizes.
2. Lift the pressure gauge knob and turn it:
A clockwise turn will make the pressure climb steadily; a counterclockwise turn will bring about pressure decrease.
Stop turning when the target reading is achieved and secure the knob—neglect of this step might cause leakage.
3. Gauge Reading
Confirm the pressure gauge is firmly affixed to the main body, and check if the reading varies smoothly during pressure regulation.
4.Auto & Manual Drainage
Automatic Mode: When condensate in the filter housing reaches a specific fill level, the condensate discharge valve opens automatically, expelling condensate via the drain hose into a collection vessel (not supplied) until only a small residual quantity remains. Manual Mode: When water surpasses the designated level, drain it promptly to sustain optimal dehumidification performance. Press the base of the brass drain body to commence drainage
5.The maintenance indicator on the coalescing filter signals when the filter element needs replacement.
Once the indicator extends, the element must be replaced without delay.
6. The initial filtration stage segregates particles exceeding 5μm, together with condensed water and oil.
The secondary filter exhibits a fineness of 0.01μm and a separation efficiency of 99.998% for particles larger than 0.01μm.
The tertiary desiccant dryer, outfitted with desiccant beads, completes the ultimate air purification procedure.
