The air conditioning knob gun, why not closed compressed air?

Answer: compressed air pressure to adjust knob spray stepless speed regulation, but not completely off the flow of compressed air. When the pressure generated by adjusting its operation has certain effect insurance.

The air conditioning knob gun left-right rotating why barometric no change?

Answer: the first will gun from compressed air system from the adjustment knob, remove the retaining bolt, hex adjust knob check whether the air flow downward into holes. Correct installation guide insert aperture is air guns, lower handle clockwise 90 °, and then insert the retaining bolt. Special attention should be paid in load regulation strictly, before the retaining bolt knob, otherwise may access compressed air to operating personnel and personnel damage.

How should adjust when spraying gun needle position?

Answer: when spraying gun needle should try to adjust back. Avoid paint and gun acus parts in severe friction state, thus accelerating shorten the spray gun three-piece suit (cap) needle, nozzle and the using life. If you need a needle back, paint flow adjustment suggestion can choose too may be smaller diameter of nozzle types.

What is HVLP meaning? Compared with the traditional spray, is there any difference?

Answer: HVLP (High = High Volume, Low = = flow; Low Pressure and Pressure), it mainly = to spray nozzle air Pressure cowl (optimized, namely the atomized air. Coatings, HVLP than 0.7 bar atomization pressure than traditional gun 3.0 bar pressure decreased a lot. By reducing the spraying of excessive atomization. Thus greatly reduce the loss of the solvent to transfer efficiency of coating (coating to improve the utilization of traditional spray, j., 35-45 percent of transmission efficiency to 65%.
