IAS-1 Product Guide
5.5

Bends

Bends are either 45° or 90°. For 90° bends, it is important that swept bends are used and not sharp elbows, as
this will introduce unnecessary pressure losses, and increase the response times from holes beyond the
bend.
5.6

Exhaust

In most installations the exhaust should be left open but there are some circumstances when it may be
necessary to connect pipe to the exhaust port to divert the exhaust away from the location of the unit e.g. to
reduce noise, reduce risk of interference/deliberate obstruction, improved environmental protection etc.
Pipe of the same specification as the sample runs should be used and its length limited to a maximum of 10 m
(33 ft) to avoid significant reduction in the airflow. Care should be taken to position the new exhaust outlet
where it cannot be accidentally or deliberately blocked.
5.7

Filters

The sampled air is passed through a filter (order code FL53) before entering the detector chamber.
Additional filtration of sampled air may be required in harsh environments. Refer to the Xtralis Inline Filter
Application Note (17785) for further information.
