Options and Accessories for XCR/XIR

Grille Options:

• Designer - Standard Grille
• Decorative - Lighted and non-lighted
• Aluminum - White enamel finish
• Stainless Steel - Polished stainless steel finish

Round Duct Connection – Standard - Sizes A50, A70, and A90

Round Duct Adapter – Optional - Sizes A110 through A510

Exclusive Electrical Wiring Feature – Accurex XCR-A models are the only fans of this type with an electrical access cover located on the housing exterior. This feature permits external wiring without removing the power assembly, saving installation time and cost.

Vertical Discharge – Exhaust outlet duct may be installed in the optional vertical position. The power assembly must be rotated to match the duct adapter position.

Double-Wide Fans – Available for applications requiring 700 cfm or greater. Double-wide fans have two double-width forward curved wheels, which are housed in separate scrolls, and driven by a single motor.

Contractor 4 Paks – Save installation time and labor by installing the housing first, then installing the internal components after the sheetrocking, plastering and finishing is done:

• Housings are packaged in one box, power assembly and grille are packaged in another box
• Components are shipped to coincide with the phase of your project

Light Options - Accurex’s fan/light combination includes a prismatic or frosted lens, and compact fluorescent or incandescent lamps. Our unique light box is manufactured with a reflective material to increase the light given off by either type of lamp. UL Listed for above bathtub/showers with GFCI branch protected circuit. Available on sizes 50 - 125.

• Prismatic Lens - The prismatic lens design provides approximately 25% more light than a traditional frosted lens. The lens may be easily removed to replace light bulbs.
• Compact Fluorescent Lamps (CFL):
  • Quick start bulbs
  • Reflective light box
  • Produce 90% less heat
  • Lower energy costs
  • Two-13 watt CFL bulbs equals 100 watts of incandescent light (included)

Frosted Lens - The frosted lens option is a traditional design which lets approximately 80% of light through the lens. The lens may be easily removed to replace light bulbs.

Incandescent Lamps -

• Dimmable
• Reflective light box
• Low first-cost light
• One bulb provides up to 100 watts of light (by others)

Speed Controls - Speed controls may be used on model XCR and XIR fans for manual adjustment of the fan’s performance (for final system balancing) or to control the fan’s output in confined spaces, such as conference or meeting rooms. The fan can be adjusted to 60% of design airflow with a speed control. This reduction in airflow and fan speed is also accompanied by a reduction in noise level. Solid state speed controls are available for a range of applications up to 15 amps. Speed controls can be used to operate more than one fan if the combined total amperage of the fans does not exceed the control rating.

Switches - Switches may be used on models XCR and XIR fans to enable manual control of your fan or fan/light combination. There are several options to fit your application.

Time Delay Switch - Time delay switches save energy by automatically turning off equipment. They may be used with models XCR and XIR fans and fan/light combinations, for extended operating time of fan. Time delay switches act in the same manner as a standard switch, however, there is a delay of 1 to 60 minutes after the it has been turned off.

Motion Detectors - Motion detectors may be used with models XCR and XIR fans, or fan and light combinations. Motion detectors use a passive infrared motion detector that will automatically turn on the fan when a change in temperature is sensed. They have a viewing area of 180 degrees, however, they must be placed in the line-of-sight. They also have an adjustable time delay shutoff setting of 1 to 20 minutes.

Ceiling Radiation Dampers - The Accurex XCR-A and XCR-B ceiling radiation dampers are UL Classified, rated at three to four hours fire resistance, and are available on all XCR-A and XCR-B fans and fan/light combinations. This design saves space by allowing the damper to mount directly beneath the fan.

Filters - Fans used in most applications, even where air is not excessively dirty, will collect airborne dirt on wheels and motors over time. Accumulations of dirt on the fan wheel will sharply reduce performance and cause imbalance. Dirt buildup on the motor can cause it to overheat. All of these conditions will shorten the life of the fan. To help reduce this accumulation, washable aluminum mesh filters are available to trap dirt before it enters the fan. These filters should be regularly cleaned to maintain performance. The Filter Loss Chart shows the effect the filter will have on performance. To determine the added resistance, divide the desired cfm by the filter area (ft2). This will give FPM. Use this with the filter loss chart to get the added resistance. In addition to reducing dirt accumulations on the motor and wheel, filters also reduce sound levels.
