It’s not the quietest unit in its class—the AC three-speed motor hums a bit more than a DC alternative, so if absolute silence is your deal-breaker, you’ll want to look elsewhere, but for most residential or small commercial spaces the noise level is perfectly acceptable during normal hours.
Basically, what it does is pull in fresh air while recovering about 70% of the heat from the exhaust stream, which pretty much means you’re not just venting all your conditioned air outside, and we’ve had buyers tell us it really takes the edge off winter heating bills for a small apartment setup.
PM2.5 filtration hits >95%, teh airflow ranges form 200 to 400 CMH (usually you’ll run it at the middle speed for a decent balance), and it’s built with zinc-free galvanized steel—that matters if you’re in a coastal area where salt air eats standdard galvanized stuff faster.
Most orders come in for the LCD controller option—makes adjusting the three speeds a lot easier than the basic switch—and we typically stock the DX1.5B4 model, so lead time is about 20 days or so for an MOQ of 50 units, bulk pricing our company can negotiate if you’re above 100.
Installation is ceiling-suspended or side-mounted, and the access door for maintenance is actually pretty handy (usually you just pop it open to swap the filter), though one thing buyers don’t always think to ask is the internal circulation mode—it recirculates inside air when the outdoor air quality is garbage, so it works as an air purifier in a pinch.
We do have the ISO, CE, and CCC certs on file, and COAs are included per batch—just confirm your shiping address and we’ll send the TDS along with quote.
Our standard MOQ is 50 units per model, but we can discuss smaller trial orders if you're just getting started. Just reach out to us directly.
Lead time is usually around 25-30 days from order confirmation, depending on stock levels. If you need a rush order, let us know and we'll see what we can do.
Yes, we include copies of our ISO, CE, and CCC certifications with every order. Just request them when placing your order and we'll make sure they're in the package.
The three-speed switch lets you manually choose low, medium, or high fan speed. The LCD controller gives you more precise control and displays real-time settings, plus it's easier to mount on a wall.
Yes, it's designed for ceiling suspension or side mounting, so drop ceilings work fine. The optional internal circulation mode recirculates indoor air without needing extra ductwork — just a simple setting change on the controller.
