DPT Series Split Multi-Inlet Duct Fan (Multi-Port Type)

This multi-port split duct fan adopts dual air inlet + 90° elbow air channel full metal structure, powered by 220V single-phase household electricity. It realizes dry-wet separated ventilation for bathroom shower area and toilet area simultaneously, with low/high two airflow grades, widely used in residential bathrooms, hotels, supermarkets and entertainment venues.

Core Product Features

Structural & Performance Advantages

· Dual Air Inlet Separate Ventilation Design: Two independent air intake ports, can connect pipelines to shower wet zone and toilet dry zone separately, realize dry-wet partition exhaust at the same time, avoid cross mixing of humid steam and peculiar odor.

· 90° Integrated Elbow Air Path: Vertical double inlet + horizontal single outlet 90° bent structure, suitable for narrow ceiling corner installation, saves pipeline turning accessories and construction space.

· Full Metal Stamped Cabinet: Anti-rust, impact-resistant, stable in long-term high humidity bathroom environment, longer service life than plastic duct fans.

· High-Quality Silent Ball Bearing Motor: Low operating noise, stable continuous operation, suitable for quiet hotel rooms and family rest spaces.

· Compact integrated body with reserved long mounting holes, supporting ceiling concealed hoisting & wall-mounted installation, easy disassembly for cleaning and maintenance.

· Each model has Low speed (L) / High speed (H) two power & airflow options, flexible exhaust volume adjustment according to space pollution degree.

Working Principle

The built-in centrifugal impeller generates negative pressure inside the cabinet, simultaneously draws humid steam from shower area and odor air from toilet through two independent air inlets, then discharges mixed turbid air outdoors uniformly via one horizontal outlet, completing synchronous exhaust of dry and wet zones in one unit.

Typical Application Scenarios

· Civil: Household split bathrooms (separate shower & toilet), apartment restrooms

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

· Matching demand: Small spaces needing simultaneous exhaust of two independent zones, narrow ceiling installation conditions, low noise rest environment

Usage Restrictions

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

· Installation: Ceiling concealed hoisting is recommended; reserve enough horizontal pipeline space at the air outlet side.

· Operating temperature: -10℃ ~ 45℃; avoid long-term direct flushing by hot steam.

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