Fresh Air Ventilation Systems for Healthier Indoor Spaces
Closed indoor spaces can trap humidity, odours, pollutants and stale air. Opening windows may not always provide consistent ventilation, especially in modern homes, offices and commercial buildings.
Amaryllis fresh air systems bring outdoor air indoors while supporting efficient airflow, filtration and air extraction. The range includes solutions for single rooms, ducted spaces and complete balanced ventilation systems.
Why Choose a Fresh Air System?
Fresh air ventilation systems help:
- Introduce fresh outdoor air
- Extract stale and unwanted indoor air
- Support balanced air circulation
- Control humidity and lingering odours
- Filter dust, pollen and airborne particles
- Improve comfort in enclosed spaces
- Reduce energy loss through heat recovery systems
The right solution depends on the space size, ventilation requirement, ducting layout, filtration needs and installation type.
Dual Direction Fresh Air (DFA): Balanced Supply and Extraction
DFA systems simultaneously introduce fresh outdoor air and extract stale indoor air, helping maintain balanced ventilation across connected spaces. Independent supply and exhaust airflow support consistent indoor air circulation. A slim, durable metal body simplifies concealed installation, while the energy-efficient copper motor with ball bearings provides stable airflow with low-noise performance.
Key features: Independent fresh-air supply and stale-air extraction, balanced ventilation, energy-saving copper motor, ball bearings, stable airflow, low-noise operation, slim body and durable metal construction.

Energy Recovery Ventilation (ERV): Fresh Air with Energy Recovery
ERV systems continuously replace stale indoor air with fresh outdoor air while recovering thermal energy from the outgoing airflow. This helps pre-condition incoming air and supports greater energy efficiency and year-round comfort. The slim unit design saves installation space, while accessible filters and internal components make routine inspection and maintenance more convenient.
Key features: Balanced fresh-air supply and extraction, heat recovery, energy-saving operation, multi-speed airflow, heat-recovery filtration, low-noise performance, slim unit design and easy maintenance.

Fresh Air Fan (FAF): Continuous Outdoor Air Supply
Fresh Air Fans are designed to bring a steady flow of outdoor air into enclosed spaces through ductwork. They are suitable where continuous fresh-air supply is required without a separate extraction function. The full-metal casing provides durability, while the slim design requires less installation space. Flexible adjustment also supports different applications and compatible two- or three-head duct arrangements.
Key features: Continuous outdoor-air supply, energy-saving copper motor, ball bearings, stable airflow, low-noise operation, durable metal casing, flexible duct adjustment and slim design.
ICONIC Filter Box: Cleaner Air Through Multi-Stage Filtration
The ICONIC Filter Box works with a compatible ventilation system to filter incoming air before it reaches the indoor space. Its multi-stage filtration captures dust, pollen, hair, smoke, odours and fine airborne particles. Filtering the incoming airflow also helps protect downstream ventilation equipment, supporting cleaner operation and reliable long-term performance.
Key features: Pre-filter, activated-carbon filter, fine-particle filtration, dust and pollen capture, odour reduction, PM2.5 filtration, smooth airflow and ventilation-system protection.
ICONIC-160: Single-Room Heat Recovery Ventilation
ICONIC-160 provides fresh-air supply, stale-air extraction and heat recovery within a compact single-room system. Its ceramic heat-exchanger core recovers up to 92% of heat from outgoing air to pre-condition the incoming airflow. Fine dust and pollen filtration support cleaner air, while the reversible DC motor switches between supply and extraction. Remote control and adjustable speed settings provide convenient everyday operation.
Key features: Up to 92% heat recovery, ceramic heat-exchanger core, fresh-air supply and extraction, fine dust and pollen filtration, reversible DC motor, remote control and adjustable speed operation.
How to Choose the Right Fresh Air System
Consider these factors before selecting a solution:
- Ventilation requirement: Decide whether the space requires fresh-air supply only or balanced supply and extraction.
- Heat recovery: Choose an ERV or ICONIC-160 when reducing thermal energy loss is important.
- Space coverage: ICONIC-160 is designed for a single room, while DFA, ERV and FAF systems support ducted applications.
- Filtration needs: Add a compatible Filter Box when enhanced incoming-air filtration is required.
- Ducting layout: Check duct diameter, length, bends and available installation space.
- Airflow capacity: Select the model according to the room volume and required air changes.
- Maintenance access: Filters, motors and internal components should remain accessible for inspection and cleaning.
Frequently Asked Questions
What does a fresh air ventilation system do?
A fresh air system introduces outdoor air into an enclosed space. Depending on the system, it may also extract stale indoor air, filter incoming air or recover thermal energy.
What is the difference between DFA and FAF?
DFA provides independent fresh-air supply and stale-air extraction for balanced ventilation. FAF primarily supplies fresh outdoor air and can be used where separate extraction is already available or not required.
How is an ERV different from a standard fresh air system?
An ERV exchanges indoor and outdoor air while recovering thermal energy from the outgoing airflow. This helps pre-condition incoming air and reduce ventilation-related energy loss.
Why is a Filter Box used with a ventilation system?
A Filter Box captures dust, pollen, smoke, odours and fine airborne particles before the air enters the occupied space. It also helps protect connected ventilation equipment.
Is ICONIC-160 suitable for a single room?
Yes. ICONIC-160 is designed as a compact single-room heat recovery ventilation solution, combining fresh-air supply, extraction, filtration and heat recovery.
Does fresh air ventilation replace air conditioning?
No. Air conditioning primarily controls indoor temperature, while fresh air ventilation replaces stale indoor air with outdoor air. Both systems can work together to improve indoor comfort.
Better Indoor Air Starts with Fresh Air
Effective ventilation is more than simply moving air. It requires the right balance of fresh-air supply, stale-air extraction, filtration and energy efficiency. The Amaryllis Fresh Air range offers flexible solutions for individual rooms, homes, offices and commercial spaces, helping create fresher, more comfortable and better-ventilated indoor environments.
