상품 소개

The broad DN250 passage houses a mechanical blade and damping system that respond to duct pressure. This selection uses a conservative portion of the available flow envelope for substantial constant-volume supply or extract duties.

Applications

Large constant-volume supply branches
Substantial extract headers

Solutions for Your Application

The branch needs more volume than smaller controllers provide.

The DN250 casing accommodates the selected higher-flow operating band.

A fixed balancing blade cannot compensate for pressure variation.

The mechanical regulating assembly changes the blade angle in response to the duct condition.
