Fan/Filter Units (FFUs) and Power Distribution Modules

View Power Configuration
Dramatically simplifies connection of ceiling lights and fan/filter modules (FFUs) and allows operation from a single Control Panel (no. 6600-23, order separately). Each accommodates up to 5 lights and 5 FFUs and includes a step-down transformer for low-voltage control and operation status indicator circuits. Includes relays and circuit breakers for overload protection of all connected devices, AC contactors, and NEC-compliant quick-connect fittings for lights and FFUs. Price includes installation on specified Terra cleanroom. Each module must be wired to a dedicated 20A fused 120 or 240VAC circuit.

Power Distribution Module, Single Point of Connection

View Power Configuration
Similar to the unit above, but includes NEC electrical enclosure mounted to the side of the cleanroom that provides easy access to serviceable components, including circuit breakers. Electrical panel allows multiple Power Distribution Modules and all other cleanroom electrical equipment to be hard-wired to a single dedicated power source, reducing reliance on an electrical contractor to complete cleanroom installation.

UL listed and CE marked models available; inquire when ordering

HEPA or ULPA Fan/Filter Unit (FFU)

• Quiet, low-vibration design: only 49 dBA, measured 30" from filter face @ 90 FPM
• Low-profile design allows installation of a 7'-high cleanroom beneath a standard 9' ceiling
• Provides an average air flow velocity of 90 feet per minute (.45 m/sec) and air flow of 600+ CFM under filter load, per cleanroom standards (2' x 4' model)
• Three-speed switch (on 2' x 4' models) provides low, medium and high settings
• Meets IEST Recommended Practices

These reliable, self-powered Filter/Fan Units provide a reliable flow of microfiltered air to meet cleanliness standards down to Class 1 (ISO 3). See Application Guidelines for filter application guidelines.

Advanced baffling technology ensures uniform airflow across the filter face and attenuates sound for quiet operation: approximately 49 dBA. Select HEPA (High-Efficiency Particulate Air) filters, rated 99.99% efficient @ removal of particles 0.3µm and larger, or ULPA (Ultra-Low Penetration Air) filter, rated 99.9995% efficient @ removal of particles 0.128µm and larger.

The durable powder-coated steel lid and body features a slide-in prefilter, for easy replacement and maintenance. The 2 x 4 models use a 3-speed, centrifugal-type fan/motor with permanently lubricated bearings. Other sizes use a speed control for a full range of settings.

All prices are for turnkey systems and include wiring and panel-mount on/off control. Gel-sealed, DOP-tested, and CE marked units available; call Terra for pricing.

EnergySaver Filter-Fan Unit Control —
Cuts Operating Costs and Heat Generation!

• Programmable filter/fan unit control lets you adjust blowers individually from a central monitor/display panel
• Independent blower control (20 – 100% full speed) allows variable flow rates within a single cleanroom
• “Not-In-Use” setting maintains desired cleanliness at lower fan speeds to save energy, cut heat generation when room is unoccupied
• Passcode security protection guarantees tamper-resistant FFU operation
