Accessories

8.2 Air Purge Collar

The Air Purge Collar accessory is used to keep dust, moisture, airborne particles, and vapors away from the optical headʹs lens. It can be installed before or after the bracket. It must be screwed in fully. Air flows into the 1/8” NPT fitting and out the front aperture. Air flow should be a maximum of 0.5 ‐

1.5liters/sec (1 ‐ 3 cfm). Clean (filtered) or “instrument” air is recommended to avoid contaminants from settling on the lens. Do not use chilled air below 10°C (50°F). Also provided is a stainless steel protection tube, 150 mm (6 inches) long by 25 mm (1 inch) diameter that threads onto the front of the air purge collar.

8.3 Protection Tube

The protection tube is available as an accessory. It is 305 mm (12 in.) long and 32 mm (1.26 in.) in diameter and comes with ¾” NPT external thread at one end. The optical head is threaded with the protection tube. The use of the air purge collar in the same time is possible.
