Spray gun pressure tanks or pots.
Using paint pressure pots to spray paint can have many advantages and speed up production spray painting processes considerably.
One of the most obvious benefits of using a remote pressure pot rather than a suction or gravity paint pot attached to the spray gun is the weight reduction and the ability to manoeuvre the spray gun into any position due to the removal of the paint pot from the gun.
Pressure pots for paint spray guns are typically available in 2 Litre, 4 Litre, 5 Litre, 10 Litre, 20 Litre, and 40 Litre sizes and it is possible to attach more than one spray gun to a pressure pot. These larger paint reserves allows a dramatically increased continuous spray painting operations compared to the 600 mL to 1000 mL capacity pot is attached directly to spray gun.
While it is possible to attach most good-quality suction spray guns to a pressure pot, the benefits will only be realised when a dedicated pressure feed spray gun is used. Dedicated pressure feed spray guns do not require any of the air flow to be expended drawing paint from a siphon pot. Dedicated pressure feed air spray guns usually always have higher flow air caps which are able to atomise higher volumes of paint which is achievable when paint is supplied to the gun from a pressure pot.
Any quality pressure feed spray gun in conventional, HVLP or LVLP will be capable of much wider spray fan patterns and much higher fluid outputs then siphon or gravity feed variants of the spray guns.
The actual pressure pot will use negligible volume of air is only air volume to displace used paint is required. Spray painting pressure pots require very low-pressure typically less than 10 PSI and more commonly between 5 to 7 PSI. On the other hand dedicated pressure feed spray guns will typically use larger volumes of air which is required to atomise the higher volumes of paint that can be applied with a pressure feed gun.
Typically the fluid nozzle and needle size should be reduced considerably from the needle nozzle size that with the use for a gravity or suction spray gun. A 2 mm needle nozzle size for a pressure feed gun is very large wear by comparison to millimetre needle nozzle size conventional gravity or suction feed spray guns is approximately little of the range. Always consult paint manufacturers recommendations in conjunction with the spray gun manufacturer recommendations to determine the correct needle nozzle size pressure feed spray gun to see your spray painting application.
