One-Way Fresh Air Ventilator-Quiet HEPA Filter

Single Direction Fresh Air Ventilator | One-Way Fresh Air Supply System for Homes & Offices

PRODUCT DESCRIPTION:

Our galvanized single direction fresh air ventilator is built for reliable one-way fresh air supply in homes, offices and commercial rooms. The SGCC galvanized steel housing protects a multi-stage filtration system — washable G4 pre-filter, F7 medium filter, activated carbon and HEPA 13 — that removes PM2.5, dust, pollen and odors before clean air is delivered into the room. The one-way fresh air flow creates positive pressure that pushes stale air, CO₂ and odors out through kitchen and bathroom exhausts. Equipped with an energy-saving EC motor and low noise from 35dB, this ducted fresh air ventilator connects to standard circular ducts for flexible ceiling or wall installation.

Product Data

How a One-Way Fresh Air System Works

Outdoor air is drawn in through the intake grille of the fresh air ventilator.
The air passes through multi-stage filters — washable G4 pre-filter, F7 medium filter, activated carbon and HEPA 13 — which remove PM2.5, dust, pollen, odors and VOCs.
Purified fresh air is supplied into the room, creating positive pressure that pushes stale air, CO₂ and odors out through kitchen and bathroom exhausts.

Because the system only moves air in one direction, the structure is simpler than a two-way unit, which means fewer parts, lower cost and easier maintenance.
