PAA1 Air Atomising Spray Nozzle Bodies
The PAA1 Air Atomising Spray Nozzle Body is an automatic pneumatic spray gun designed for controlled, repeatable spraying where precise ON/OFF liquid operation is required. An internal air-operated cylinder controls the opening and closing of the liquid supply, allowing operation at over 100 cycles per minute.
The PAA1 incorporates an internal needle that not only performs the ON/OFF function but also cleans the nozzle orifice, helping maintain consistent operation. Separate connections are provided for atomising air, liquid and pilot air, with 1/4" female connections for air and liquid and a 1/8" female pilot-air connection.
- Automatic air atomising spray nozzle body for controlled spraying applications.
- Pneumatically operated internal cylinder provides automatic ON/OFF liquid control.
- Capable of over 100 operating cycles per minute.
- Internal needle performs both the ON/OFF action and cleaning of the nozzle orifice.
- Separate connections for atomising air, liquid and pilot air.
- 1/4" female air connection.
- 1/4" female liquid connection.
- 1/8" female pilot-air connection for operation of the internal piston.
- Incorporates separate air and liquid nozzles within the spray gun assembly.
- Internal assembly includes Teflon sealing components.
- Designed for automated and repetitive spraying processes requiring rapid spray start/stop control.
More Information
The PAA1 Air Atomising Spray Nozzle Body provides an automated solution for applications requiring controlled pneumatic atomisation combined with rapid, repeatable switching of the liquid supply. The design uses an internal air-operated cylinder to control liquid ON/OFF operation, enabling the spray to be started and stopped automatically rather than relying on manual control. The PA/PAA automatic spray gun design is capable of more than 100 operating cycles per minute, making it suitable for repetitive and intermittent spraying processes.
Separate supply connections accommodate the air and liquid required for atomisation, together with a dedicated connection for the pilot air that operates the internal piston. On the PAA1 configuration, the air and liquid supplies use 1/4" female connections, while the pneumatic pilot supply uses a 1/8" female connection. This arrangement provides independent control of the spraying media and the pneumatic ON/OFF mechanism.
A key feature distinguishing the PAA1 is its internal cleaning needle. In addition to controlling the opening and closing operation, the needle passes through and cleans the orifice during operation. This automatic orifice-cleaning action is particularly useful where maintaining a clear spray opening and dependable operation is important.
The assembly incorporates separate liquid and air nozzles along with the gun body, internal needle, springs, seals, washers and associated retaining components. The construction also incorporates Teflon sealing components around the needle assembly.
Overall, the PAA1 combines pneumatic atomisation, automatic liquid shut-off and integrated orifice cleaning in a single spray nozzle body, providing a practical choice for automated spray installations requiring frequent switching and controlled spray operation.
FAQ
Both models share the same principal connections and pneumatic ON/OFF operation. The distinguishing feature of the PAA1 is its internal needle, which also cleans the nozzle orifice as part of its operation.
The liquid supply is opened and closed by an internal pneumatic cylinder. A separate pilot-air connection operates the internal piston, providing automated ON/OFF spray control at a rate of over 100 cycles per minute.
The PAA1 has 1/4" female connections for the atomising air and the liquid being sprayed, together with a 1/8" female connection for pilot air used to control the internal pneumatic piston.
Yes. The PAA1's internal needle carries out the normal ON/OFF function while also cleaning the orifice, providing an integrated cleaning action as part of the spray gun's operation.
