S&P TD Series Inline Fans

The S&P TD-MIXVENT series of in-line duct fans have been specially designed to maximize the airflow performance with minimal noise levels within the smallest and most compact housing size. This makes the TD-MIXVENT series the ultimate solution for applications which require a high airflow to pressure ratio and occupy only the minimum space possible. Example: false ceiling voids, cabinets and many other limited space environments. Great for bathroom, kitchen and general venting applications.

The TD-MIXVENT models 100, 100x1, 125,150, and 200 are manufactured in tough reinforced plastic, models 250 and 315 have a metal casing and are finished in a tough epoxy-polyester paint coating. Fully speed controllable.

#1 Q:   Are these fans rated for exterior roof top installation as an exhaust fan. Im looking at the TD 250
A:   They are not. They must be protected from the elements.

       Asked on 2024-01-07 by MD
#2 Q:   Can the TD-200 be installed in an insulated box?
A:   Yes. It does not require external air over the casing.

       Asked on 2020-12-29 by JB
#3 Q:   How noisy is the regular fan? If mounted on the truss that the wood ceiling is attached to will there be a lot of vibration? If so is there any way to dampen it?
A:   Would depend on size...the 6 inch is about 58 decibels. They are pretty well balanced, but you could definitely put a neoprene pad in between the mount foot and truss to catch any vibrations.

       Asked on 2019-12-28 by Sean

A:   Depends on your application. If bathroom exhaust see theis bath guide that gives you sizing criteria for different size rooms: https://www.hvacquick.com/catalog_files/solerpalau_Bathroom_Exhaust_Brochure.pdf

       Asked on 2019-10-26 by Randy

       Asked on 2018-12-30 by Doug
#11 Q:   I need to increase cool air velocity going down stairs. Can this work in my A/C system for cooling? How low a temperature can the plastic fan blades handle?
A:   The TD fans are commonly used for boosting. Heating or cooling. The blades can easily handle the cool temps - they are commonly used for fresh air intake in cold climates where the temps are much lower than A/C.

       Asked on 2018-10-29 by Tropikal
#12 Q:   Can this be mounted in any direction? My application would be wall mounted straight up and down with airflow going vertically from top to bottom.
A:   Up/down orientation is fine for these. Make sure you have a few feet of the flex duct between the fan and the bathroom so that any fan noise is taken out by the duct.

       Asked on 2018-10-05 by Thomas
#13 Q:   Would I be able to trim the ends of the TD125? I only have 9inches of height to fit it in.
A:   Not much to trim. There is only enough flange to slide the duct over and secure it. The full length is 10-3/16 inches.

       Asked on 2018-07-22 by Joseph
#14 Q:   Used as a booster fan in an existing HVAC system with 10 round duct:Can the TD-250 be mounted vertically rather than horizontally? Capable of continuous duty (running continuously for 3 months)?

#19 Q:   Does it automatically turn on and off with the furnace or does it run all the time?
A:   If wired directly, it would run continuously...You could use a pressure switch if you would like it to run when the furnace or AC is on.

       Asked on 2014-11-14 by Brendon
#20 Q:   Hello, im looking for a small compact blower/ inline fan for a car air purifier i am buliding. it would have to pull air through a carbon and a hepa filter and be quiet enough to run in a car. Do you think this inline fan is up to the task?
A:   The TD fans typically dont have enough resistance to pressure for them to pull through a hepa and carbon filter. The fans that do have that capacity will be louder, also these fans run on 120v so you would need an inverter to convert the power.

       Asked on 2014-06-24 by Blair
#21 Q:   can this fit between inside and outside wall (4 & one half in ) can i buy & inside grill
A:   As the smallest one is 9 inches long, it would need some added material to fully cover than fan.

       Asked on 2013-05-01 by Geoff
#29 Q:   Can these be used for dryer boosting?
