FFU ومعدات تنقية الهواء الطرفية
وحدة تصفية مروحة عالية الضغط الثابت
A deep-plenum FFU for cleanroom duties with added air-path resistance, combining a backward-curved EC fan, reinforced casing and pressure-test access.
- بضغط معزز عميق
- Backward-Curved EC Impeller
- Accessible Pressure-Test Port
- Variable-Speed Fan Adjustment
مقدمة المنتج
The high-static-pressure fan filter unit combines a backward-curved EC impeller, deep inlet arrangement and reinforced plenum. Formed ribs and corner reinforcement support the casing, while a capped test connection provides access for pressure measurements. The unit is intended for cleanroom selections in which inlet losses or final-filter resistance are important parts of the airflow duty. Pressure capability is evaluated at the required flow, not from the motor size or housing depth alone.

Variable EC fan speed provides an adjustment range for balancing the selected fan and filter combination.
حلول للتطبيق الخاص بك
A high-resistance duty needs an airflow-and-pressure selection for the complete installation rather than a maximum-pressure figure in isolation.
An added duct collar changes the inlet condition assumed for an open-plenum selection.Include the actual duct and fitting losses when selecting the operating point.
Available airflow can fall as final-filter resistance increases.Check the loaded-filter duty against the fan curve and permitted operating range, rather than assuming the controller can always restore flow.
Higher internal pressure places additional demand on casing joints and filter seals.Pair the reinforced housing with the specified filter interface and inspect the assembled seals during commissioning.
A pressure reading alone cannot identify every cause of low airflow.Record inlet pressure, filter differential pressure and delivered airflow together to separate air-supply, filter and fan-setting issues.

Pressure-Duty Selection and Installation
Define the full resistance path
For a quotation, state the required airflow and external losses at that airflow, including inlet ductwork, fittings and any prefilter. List the final-filter resistance separately so that internal filter pressure drop is not counted twice. The selected fan curve must cover both the clean-filter duty and the intended loaded-filter limit.
Match the inlet and control arrangement
Choose an open intake or a dimensioned duct collar, the final-filter grade, and the gasket or gel-seal construction. An EC motor does not by itself establish constant-airflow operation. Where an upstream air-control device is used, select compatible control behaviour rather than allowing two independent controllers to regulate the same airflow.
Install for measurement and service
Allow access to the test connection, motor controls and filter removal path. Use the specified ceiling support layout and electrical rating, and measure delivered airflow as well as pressure during balancing. Disconnect power before filter or fan maintenance.
A standard fan filter unit may suit a lower-resistance ceiling duty. If the main requirement is increased total volume across a broad outlet, compare the high-airflow fan filter unit.
