Delta Breez SLM70 – Frequently Asked Questions

1) What size duct does the Delta BreezSlim SLM70 bath fan connect to?
Three inch duct. The SLM70 is built around a 3 inch duct diameter, which is smaller than the 4 inch most older bath fans run. If the ceiling already has 4 inch flex or rigid duct in place, you need a 4 to 3 inch reducer at the fan collar to make the connection, so add that to the order before the crew is in the attic.
2) Can the SLM70 Delta Breez fan be mounted on a wall, or is it ceiling only?
Both. The BreezSlim SLM70 is UL listed for ceiling mount and wall mount installation, which matters in a bathroom with no attic above it or a half bath on an exterior wall where the run has to go straight out sideways.
3) Is 70 CFM enough for the bathrooms in my apartment units?
70 CFM covers a bathroom up to about 70 square feet under the usual one-CFM-per-square-foot rule of thumb, so it suits the typical multifamily 5x8 bath with a tub or shower, toilet and vanity. The SLM70 runs at full speed only, single speed, so there is no low setting to trim it down; if you want continuous ventilation at a lower rate plus a boost, you want a multi-speed fan instead.
4) Does the Delta Breez SLM70 meet California Title 24 for a bathroom exhaust fan?
Yes, the SLM70 is California Title 24 compliant, and it is ENERGY STAR qualified. For a spec job in California that pairs of ratings is usually what the inspector and the energy consultant want to see on the submittal.
5) How quiet is the Delta BreezSlim SLM70, and will tenants complain about the noise?
Rated 1.5 to 2.0 sones depending on static pressure, and Delta states 2.0 sones for the fan as installed. That is in the range people describe as background noise rather than a roar, and the DC brushless motor is what holds it there. Ducting matters: the quieter end of that range is at low static pressure, so a short straight run with smooth duct keeps it near 1.5, while a long crushed flex run pushes it to the top of the range.
6) Does the SLM70 come with a wall switch or do I need to supply one?
The SLM70 is a single speed fan wired to a standard wall switch, and Delta publishes a single wall switch set up sheet for it. Plan on the electrician providing the switch and, if the job calls for it, a timer or humidity sensing switch in its place, since the fan itself has no onboard control.
7) Can I buy the Delta BreezSlim SLM70 in bulk for a multifamily job?
Yes. Delta offers the BreezSlim in contractor packs, which is how these get bought for multifamily and single family production work where every bath gets the same fan.
8) What are the shipping carton dimensions for the Delta BreezSlim SLM70?
The boxed SLM70 measures 10-3/4 inches wide by 9-3/8 inches deep by 4 inches high. Useful when you are staging a contractor pack of them on a job site or figuring out van space for a unit turn.
