Description for Fantech SH704

A Heat Recovery Ventilator is a complete whole house ventilation system that incorporates a supply motor and an exhaust motor in one unit. It is designed to bring a continuous supply of fresh air into the home while exhausting an equal amount of contaminated air. HRVs use what is known as a "sensible" heat recovery core. The special aluminum core transfers heat from the exhaust air stream to the incoming air stream. Fresh incoming air is tempered by the heat that is transferred from the outgoing air so you save on energy costs. HRVs are designed for colder areas of the country that have longer heating seasons as well as drier desert areas of the South.

Features:

  • Powder coated 24-gauge galvanized steel cabinets
  • Fully insulated with 1" aluminum foil-face high density foam
  • (2) German manufactured motors with backward incline impellers
  • Aluminum heat recovery core
  • Small compact size
  • Includes easy-mount wall bracket
  • Single speed ventilation
  • No controls needed
  • No balancing required
  • Automatic exhaust defrost allows units to always stay in ventilation mode
  • 3' plug-in power cord
  • (2) Electrostatic filters (washable)
  • 64-67 CFM (31-32 L/s) at 0.3" wg or 55-56 CFM (26 L/s) at 0.4" wg
  • 4" side port duct connections

              Used this product in a 1200 sq.ft. house. Moves more air(1400 cfm) than is needed. A 36 to 53 cfm unit is better suited for this small house

                    Could have purchased locally at supplier but no one stocks these around central ohio area, plus they wanted 25% more and would need 2 to 3 weeks for delivery.my first thought went to Pexsupply and if they would have it in stock, they did have as well as being much more affordable. Installed at customers home and they absolutely love the fresher air in their home. Wonderful product .

                          I purchased the Fantech SH-704 Heat Recovery Ventilator to retrofit in my 1950 mid-century home.

                          Firstly, the house had only R-12 insulation in its rafter cavities (it's a "butterfly-style" or inverted-V pitched roof) and I wanted to bring it up to code. Therefore, an in-house ventilation system was required to equalize vapor loads so that I could "dense pack" the cavities with blown-in fiberglass and not incur mildew growth.

                          I searched online and discovered the Fantech. It compared well with the other brands at its price point and (importantly) was equipped with German-made EBM roller bearing motors for quiet operation.

                          Unpacking the unit, I did notice some shipping damage to the case; light creasing due to lack of double-boxing by PexSupply. I corrected this with a ball-peen hammer. The unit had numerous assembly flaws, including the mis-positioning of opposing slider tracks (which hold the heat exchanger core in place). The door closing latch was missing a screw and was thusly loose. I spent roughly an hour re-working the tracks (and removing part of the case insulation) so that I could reliably remove and re-insert the core without binding. Furthermore, the core screens were roughly 1/4" to narrow to attach to their tracks; a duct tape flange extension was engineered. Hasty mistakes by Fantech.

                          In operation, the unit is quiet and effective. My indoor air quality has improved significantly and overall I'm pleased now with the unit. I installed an inline dimmer switch to save electricity when I'm out of town.

                          I'm giving this experience 4.5 stars with the balance on credit for Fantech and PexSupply to improve on their game. I would recommend Fantech and PexSupply with caveats: Slow down the assembly line and package more carefully. Thank you.

                          Hung from the ceiling in basement. No vibrations and very quiet. Had to purchase a condensate pump as the drain line was above the condensate output on the bottom of the unit. No big deal as the pump I purchased works great as well. The only thing I would recommend is to make sure the input duct coming in with fresh air from outside is well insulated if living in a colder climate. The condensation is fairly heavy if the basement is heated.

                            Q:

                            The manual for the SH704 shows the outside air inlet and exhaust as being on the left side of the unit and the inside air inlet and exhaust as being on the right side of the unit, which is unfortunately backward for what would work best in my case. Is it possible to swap the sides, i.e. outside air to/from the right side and inside air to/from the left side, or is there some reason that would not work? Thanks for your help.

                              A:

                              I had this same question on my unit when I went to install it. After looking at the setup and all that would require changing to have it operate the opposite way, I decided to mount my unit on the other side of the wall so I could connect everything the way it was from the factory and just build in the soffit enclosures to cover the ductwork. I was originally going to mount the unit above the kitchen cabinets and enclose the ductwork in the soffit above the cabinets. Instead I mounted it in the bathroom above the toilet and designed the soffit to include built-in LED recesses lighting over the sink area. From what I could tell, here are the items to consider for changing the connections:
                              * The supply and exhaust motors would have to be rewired or swapped to change the airflow directions. This would require dismantling the internals of the unit and opening the control boxes to access the wiring.
                              * The drain port for condensation collection would have to be moved to other side of unit and a collection well would have to be installed in bottom of unit for this drain to work right.
                              * I don't think both fans (supply & exhaust) are rated the same amperage and cfm flow, but I'm not positive. As I remember, the supply line maximum duct length was less than the exhaust line maximum duct length. So there might be issues with just rewiring the fans in place to rotate backward from what the factory direction is. The cfm flows for the unit being balanced are based on the duct maximum lengths and the head loss restrictions through the heat exchanger.
                              * You might want to check with the manufacture to see if this is possible and what other considerations are needed. In my case, relocating the unit to an opposite wall actually worked to save me time and distance for ducting runs for the supply air to individual rooms.
                              Hope this can be of some use in your particular case.

                            Q:

                            I have a single room use in mind. Can I mount this unit with the outside output and intake going through the exterior wall and the inside output and input going into the room with no ducting? Is there another unit designed specifically for this type of use?

                              Thru the wall is fine so long as its to the outside of the building.
                              Exhaust input should come from 2-3 inches off floor.

                              Yes, imagine classroom with bunch of kids, office with lots of cubicles or a gym, you need to bring fresh air in, especially if there is no operating windows, everyone will go to sleep from high levels of CO2, make sure you maintain distances between ins and outs otherwise you will be recirculating same air
                              Hope this helps, Darek.
