상품 소개

The 250 mm version is built for higher-flow supply and exhaust branches and has the largest selected impeller and motor package. A 249 mm duct spigot and 303 mm outer casing clearly distinguish it from the two smaller fans, while the 300 mm body remains compact for its airflow class.

주요 기능

Higher branch throughput

The expanded impeller serves major support-room or equipment exhaust branches without moving to a rectangular fan.

Round-duct integration

The 249 mm spigots connect directly to nominal 250 mm circular duct and common inline accessories.

Controllable motor package

The larger EC drive can be balanced to actual pressure demand rather than throttled continuously at full speed.

Applications

Higher-flow cleanroom support supply, central local-extract branches, technical-area exhaust and process-equipment ventilation.

Solutions for Your Application

A medium inline fan requires excessive speed and becomes noisy at the target volume.Use the larger 250 mm impeller and commission it at the lowest speed that satisfies measured airflow.

The heavier fan body could distort lightweight circular duct.Provide an independent bracket or suspension support and use flexible couplings instead of loading the duct joints.

사용 가능한 옵션

Variable-speed controller, suspension kit, insulated silencer, quick-release clamps, backdraft damper and inlet grille are available.
