It's built around a DC brushless variable frequency motor that basically sips power while pushing air — you're looking at 100 to 5000 m³/h depending on your setup, and the noise stays at or below 45 dB(A) even at higher speeds.
What that means in practice is you can run this thing in a hotel lobby or a hospital ward without anyone complaining about the hum, and the PM2.5 filtration catches at least 95% of fine particles, so it's actually pretty good for labs where air quality matters.

Heat recovery is either full or sensible depending on model, so you're not just dumping conditioned air outside — it reclaims some of that energy, which matters when you're covering 20 to 500 square meters of space.

We usually have stock on the galvanized steel shell version, but if you need stainless steel for a corrosive environment, that's a custom order (lead time is typically 2-4 weeks or so).

The touch panel control is straightforward enough, though it's not suited for tiny rooms under 20 m² — the airflow can't throttle down that far without losing effiency, so you'd be better off with a smaller unit.
Anyway, you'll want to specify whether it's wall-mounted, ceiling-mounted, or ducted when you order, and our company can do 220V/50Hz or custom voltage — just confirm teh MOQ for non-standerd specs.
MOQ starts at 10 units per model for standard specs, but we can negotiate lower quantities for initial trial orders.
Lead time is around 20-30 business days for standard models; custom airflow or material options may add 5-10 days.
Yes, we include certification documents with every shipment, and we can share digital copies beforehand if needed.
It stays at or below 45 dB(A) in standard operation, measured at 3 meters away under normal installation conditions.
You can pick either galvanized or stainless steel shell material; just let us know your preference when ordering.
