FE Series Bidirectional Flow Total Heat Recovery Fresh Air Ventilator

FE series ceiling-mounted bidirectional total heat exchange fresh air units are residential & commercial energy-saving ventilation equipment, adopting full heat core for energy recovery, multi-stage air filtration, dual-way simultaneous air supply & exhaust. It is widely used in residences, schools, basements and entertainment venues, with 8 airflow specifications from 250 to 2000 m³/h.

ore Product Features

Main Structural & Material Advantages

· Galvanized Sheet Cabinet: Anti-rust, stable structure, low vibration during long-term operation.

· Dual Inlet Multi-Blade Centrifugal Fan Wheel: Large air volume, low noise, stable air output.

· Adjustable Speed Controller: Multi-speed regulation to match different ventilation demand scenarios.

· Replaceable Multi-Layer Filtration System: Standard primary filter; optional medium-efficiency filter & activated carbon filter, achieving over 95% purification rate to block PM2.5, dust, bacteria and peculiar odor.

· High-Efficiency Total Heat Exchange Core: Excellent heat & moisture permeability, fixed 70% heat exchange efficiency, recovers indoor cooling/heating energy to cut air conditioning power consumption.

· Independent filter compartments for fresh air side & exhaust air side, easy disassembly for filter cleaning and replacement.

Working Principle

Two-way simultaneous air circulation:

Fresh outdoor air passes through multi-stage filters, exchanges temperature & humidity with indoor exhaust air via total heat core, then sends purified fresh air into rooms.

Stale indoor exhaust air absorbs heat/moisture from incoming fresh air, then discharges outside, realizing energy recycling and constant indoor oxygen environment.

Application Scenarios

· Civil: Residential houses, apartments, renovation houses (eliminate formaldehyde & decoration odor), basements, villas

· Commercial: Kindergartens, schools, offices, entertainment venues, small shops

· Matching demand: Spaces with poor natural ventilation, high air cleanliness requirements, constant humidity & oxygen demand

Model Selection Logic

Take FE250 as example: Suitable for 90㎡ residence with 3–5 residents, standard ventilation volume 30m³ per person per hour, solving peculiar smell, pollutant accumulation in newly renovated houses. Other models are matched according to space area, number of occupants and air change frequency requirements.

Usage Restrictions

· Indoor ceiling concealed installation only, not for exposed wall-mounted placement.

· Ambient operating temperature: -10℃ ~ 45℃; avoid long-term high temperature direct sunlight.

· Regular filter cleaning/replacement cycle: Primary filter every 1–2 months; medium-efficiency & activated carbon filter every 6–12 months according to local air quality.

· Voltage fixed at 220V 50Hz single-phase domestic power supply.
