Core Product Features

Structural & Performance Advantages

· 90° Single-Inlet Elbow Air Channel Design: Vertical air inlet + horizontal air outlet integrated 90° layout, easy to install at ceiling corners and wall gaps, saves installation space, large airflow and stable static pressure.

· Full Metal Integrated Housing: Stamped metal shell, rust-proof, firm and durable, longer service life than plastic duct fans.

· High-Quality Silent Motor: Precision ball bearing motor, stable long-time operation, low running noise, suitable for quiet rest spaces such as hotel rooms and bedrooms.

· Compact Split Integrated Body: Small size, light weight, reserved long mounting holes for wall/ceiling fixed installation, easy disassembly for cleaning and maintenance.

· Two optional speed grades (L low speed / H high speed) for each model, freely adjust exhaust volume according to space odor concentration.

Working Principle

Centrifugal impeller rotates to generate negative pressure inside the machine, draws turbid, humid and odorous air from the air inlet, and discharges outdoors through the horizontal duct outlet, realizing rapid air exchange, dehumidification and odor removal in closed small spaces.

Typical Application Scenarios

· Civil: Household bathrooms, toilets, cloakrooms, small storage rooms

· Commercial: Hotel guest rooms, supermarket restrooms, KTV, cafes, small entertainment venues

· Matching demand: Narrow ceiling / wall gap installation, low noise requirements, small-space deodorization and moisture exhaust

Usage Restrictions

· Power supply: Standard 220V 50Hz single-phase AC, compatible with ordinary household sockets.

· Installation: Wall-mounted or concealed ceiling mounting; reserve enough pipeline space at the air outlet.

· Operating ambient temperature: -10℃ ~ 45℃, avoid direct contact with high-temperature steam for a long time.

· Maintenance cycle: Clean dust and lint on impeller every 3–6 months to prevent noise increase and airflow attenuation.
