商品紹介

The high-static-pressure fan filter unit uses a larger backward-curved EC impeller, deep inlet cone and reinforced plenum to generate more pressure than a standard ceiling module. Structural ribs resist panel movement at the higher operating pressure, and an accessible test port allows the fan operating condition or filter resistance to be checked without opening the clean side. This model is suited to ducted inlets, terminal housings with dense filter packs and rooms where the airflow setpoint must be maintained through a longer loading interval.

主要な特徴

A deep inlet cone guides air smoothly into the oversized impeller and supports pressure development with less recirculation.

Formed ribs and reinforced corners limit casing deflection when the plenum operates at elevated static pressure.

A capped pressure port provides a repeatable connection point for commissioning and maintenance measurements.

The EC controller can increase fan speed progressively as filter resistance rises, within the selected operating envelope.

お客様の製品に関する懸念事項

High-resistance systems lose airflow quickly unless the fan, casing and control range are designed for the full pressure path rather than only a clean filter.

A standard FFU falls below the target face velocity when connected to an upstream duct collar.The larger impeller and deep inlet provide the added pressure reserve needed for duct and fitting resistance.

Filter loading changes the delivered airflow long before the final filter reaches a useful service limit.Variable EC speed and pressure reserve allow airflow to be maintained across a broader resistance range.

Thin plenum panels oil-can or leak at seams under elevated internal pressure.Structural ribs, reinforced corners and sealed folds stabilize the housing at the intended operating point.

Technicians cannot distinguish a loaded filter from an incorrectly set fan without opening the ceiling module.The external pressure-test port permits differential-pressure checks from the service side.
