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.

Q1: What is a bidirectional total heat recovery fresh air ventilator? What core function does it have?
A1: It is a ceiling ventilation unit that simultaneously supplies filtered fresh air and discharges stale indoor air, with a total heat core to recover 70% of heating/cooling energy, realizing energy-saving constant oxygen ventilation.
Q2: What filtration grades can this FE series be equipped with? What pollutants can it filter?
A2: Standard primary filter; optional medium-efficiency filter and activated carbon composite filter. It efficiently intercepts dust, PM2.5, bacteria, formaldehyde and peculiar odor from outdoor air, purification rate over 95%.
Q3: What is the heat exchange efficiency of this series? What energy-saving effect can it bring?
A3: Fixed 70% total heat exchange efficiency. In summer, it recovers indoor cold energy to reduce air conditioner load; in winter, it retains indoor heat to cut heating power consumption, greatly lowering HVAC operation cost.
Q4: What installation method does this fresh air machine adopt? Does it occupy indoor ground space?
A4: Concealed ceiling mounting, fully hidden inside ceiling, no occupation of indoor usable floor area, only ventilation pipes exposed at air supply/exhaust outlets.
Q5: What power supply does the FE series use? Is it compatible with ordinary household sockets?
A5: Standard 220V 50Hz single-phase AC power supply, matching common domestic and commercial socket standards.
Q6: How to select the suitable model according to house area? Take a 90㎡ house as example.
A6: FE250 is recommended for 90㎡ houses with 3–5 residents, meeting the standard ventilation demand of 30m³/h per person. Larger areas with more occupants can select FE350~FE1500 according to air change frequency.
Q7: How often do the internal filters need to be cleaned or replaced?
A7: Primary filter can be washed and reused every 1–2 months; medium-efficiency and activated carbon filters are disposable, recommended replacement every 6–12 months depending on local air quality.
Q8: What is the internal fan structure? Is the operation noise loud for bedroom installation?
A8: Adopts dual-inlet multi-blade centrifugal fan wheel, optimized mute air duct design. Minimum noise only 32dB (FE150), quiet enough for bedroom and living room all-day operation.
Q9: Can we customize special voltage such as 110V/60Hz for export bulk orders?
A9: Standard configuration is 220V/50Hz. We support customized motor and control panel voltage for large export container orders to match local grid standards.
Q10: What complete after-sales spare parts and technical support are provided for bulk purchases?
A10: Full English installation & operation manual is attached to each unit. Complete spare parts including all grades of filters, fan motors and control boards are supplied; we also provide professional pipeline layout design, ceiling installation guidance and fault troubleshooting technical support for wholesale customers.
