ファン駆動 HEPA モジュール

A ceiling supply module that combines its own fan with a replaceable HEPA filter, useful where terminal filtration needs local airflow adjustment and accessible servicing.

商品紹介

The fan-powered HEPA module places a fan chamber above a final-filter frame within a ceiling-mounted enclosure. The room-facing diffuser opens to expose the filter-retention area, while the housing remains supported overhead. Air can enter from an open ceiling plenum or through a selected duct collar. This arrangement suits a new or replacement terminal supply point where filter access and individual adjustment are important, without treating the unit as a complete ventilation or air-conditioning system.

主要な特徴

Local terminal fan

The integrated air mover allows the terminal supply point to be selected around its filter and upstream air path rather than relying only on central duct pressure.

Downward filter removal

The accessible room-side frame provides a replacement route without lifting the complete housing out of the ceiling.

Alternative inlet layouts

A selected collar or plenum intake lets the module connect to the intended recirculation or conditioned-air arrangement.

Testing access choices

Pressure and aerosol connection positions can be planned together with the diffuser and filter-service opening.

アプリケーションのソリューション

Filter access and the inlet arrangement should be resolved before the ceiling is closed.

A proposed HEPA outlet exceeds the remaining duct pressure.Review a fan-powered terminal at the required flow and full system resistance instead of assuming the central fan can absorb the additional filter loss.

The ceiling void is inaccessible for routine filter changes.Use a room-side replacement arrangement and reserve a clear downward removal area for the selected filter.

A retrofit location has room for a module but not for an inlet duct bend.Compare the complete installed heights of the ducted and open-plenum versions while checking whether local recirculation suits the room air balance.

Maintenance staff cannot reach a required test connection.Locate the injection, sampling and pressure connections by their actual test functions before ordering the face and filter frame.

技術的なパラメータ

Common ceiling-module sizes and selectable inlet, filter and control arrangements help define the required supply point.

Common Nominal Ceiling Formats	600 × 600 mm or 600 × 1200 mm; actual casing and ceiling opening depend on the mounting system
Typical Module Body Depth	Approximately 275–400 mm for compact fan/filter bodies, before added inlet collars or service extensions
Common Housing Options	Powder-coated steel, aluminium or 304 stainless steel
Fan Configuration	Integrated EC fan with a compatible speed controller
Common Electrical Supply Options	220–240 V AC, single phase, with the matching 50 Hz or 60 Hz variant
Common HEPA Filter Options	H13 or H14 mini-pleat filter, with an aluminium or alternative compatible frame
Filter Sealing Options	Compression gasket or gel-seal interface selected with the filter frame
Inlet Arrangement	Open-plenum intake or ducted inlet collar
Control Options	Standalone speed adjustment, 0–10 V input or a compatible network controller
Service Arrangement	Removable room-side diffuser and downward final-filter replacement
Optional Test Connections	Filter pressure and aerosol connections positioned for the selected access arrangement
カスタマイズ	意図したアプリケーションと動作環境に基づいて利用できます。

Select the inlet, filter-service frame and control hardware together. Network capability and room-side motor servicing are separate choices, not automatic features of an EC fan.

Selection and Installation

Match the inlet to the ventilation scheme

Choose an open-plenum or duct-connected inlet from the actual room air balance. Recirculated ceiling air and conditioned make-up air have different temperature, humidity and pressure conditions. A local fan can assist terminal filtration but cannot create additional outdoor air or cooling capacity. Include any collar, damper and upstream resistance when reviewing the fan's available duty.

Check the complete overhead envelope

The nominal ceiling format is not the cut-out or the casing dimension. Obtain the flange detail, support points and full installed height, including inlet collar, duct bend and cable access. The reference body-depth range excludes those additions. Keep access to the motor and electrical enclosure separate from the room-side filter-removal space.

Compare airflow and testing at the supplied configuration

Specify the required flow, clean-filter pressure loss and allowance for filter loading. Review sound and power at that same fan/filter operating point, not at free-air maximum volume. An EC drive or 0–10 V input alone does not provide automatic constant-airflow regulation. Select test and pressure connections by function; an upstream aerosol injection connection is not the same as a sampling port.

Plan replacement without disturbing the housing

Define the gasket or gel-seal frame, filter dimensions, retainer type and safe diffuser restraint. Isolate electrical power for servicing, protect the media during removal and inspect the seal after fitting a replacement. Room-side filter access does not imply room-side motor access or a hazardous-filter change system. The module supplies filtered air; sterile compounding, room classification and biological containment depend on the complete facility and process design. Compare the broader standard fan filter unit when room-side access is not the deciding requirement.
