Air Horns, Indicators & Flow Regulators
Pneumatic Audible Alarm Horns
• Thermoplastic or die-cast aluminium alloy trumpet
• Vibrating brass diaphragm
• Supplied with ttings for use with 1/4" or 6 mm OD plastic, nylon or metal
tubing
• For operation above 1.5 bar a restrictor must be inserted into the tting
• Designed and manufactured in accordance with BS EN ISO 9001:2000
The sound output of the air horns is high so care should be taken to prevent possible aural damage of operators and other personnel.
High Visibility Pneumatic Alarm Indicators
• Pneumatically operated ag with full 360° visibility moving in aluminium and acrylic housing
• Flag becomes visible on removal of the pneumatic signal; but by changing the mask within the acrylic housing this can be reversed to make the ag visible on application of the pneumatic signal
Precision Pneumatic Flow Regulators
• For use with dip tube level measurement and purging applications
• Maintains constant ow rate independent of inlet and outlet pressures • Flow rate is adjustable using the integral needle valve
• Available with variable are ow rate or without ow indication
• Designed and manufactured in accordance with BS EN ISO 9001:2000
