What is a Mechanical Ventilation System?

Mechanical Ventilation systems work by extracting stale air or supplying fresh air into rooms in a house or building. Systems such as mechanical ventilation heat recovery systems extract and supply. There are four different types of mechanical ventilation systems:

MVHR - Mechanical Ventilation Heat Recovery System

C-MEV - Centralised mechanical extraction system, most commonly known as Mechanical Extraction Ventilation (MEV)

D-MEV - Decentralised mechanical extraction system

PIV - Positive input ventilation system

Benefits of Ventilation Systems

Each mechanical ventilation system has its own specific benefits and are they suitable for many different types of applications. Our sales and technical team will be able to help you choose the correct system for your project depending on size, type of building and by what is required and will work best in the specific application.

Each system has a range of benefits including:
- Improving indoor air quality
- Eliminating risk of condensation, mould and damp
- Reducing risks of health problems cause by indoor air pollutants
- Providing clearer air that is beneficial to allergy and asthma suffers
- Quiet Operation
- Low Running Costs

“Don’t worry we can help you choose the correct system”

What is MVHR?

A Mechanical Ventilation Heat Recovery (MVHR) system is an energy recovery ventilation system that uses an air-to-air heat exchanger that recovers heat that is usually wasted. It works by supply and extracting airflows in and out of homes and buildings to ensure a better indoor air quality. Heat recovery units can recover up to 90% of normally lost heat depending on the unit and the application. A MVHR system works independently from a heating system and due to the heat recovery feature, it can have great savings on your energy bills.

A MVHR system works to eliminate condensation and mould within a building by constantly ventilating a property. By eliminating condensation, it also eliminates the risk of damage to the structure of a building and stops the build up of mould and damp. MVHR systems are suitable for small residential products to large commercial projects.

BPC Ventilation stock a large range of MVHR for both residential and commercial applications. We stock top quality units from manufactures such as:

- Vent-Axia
- Quiet-Vent
- Caladair
- Mitsubishi
- Duco
- Domus
- Xpelair
- Airflow
- Vortice
- Blauberg

What is C-MEV (MEV)?

A Centralised Mechanical Extract Ventilation (C-MEV) system is a low energy, continuous mechanical extract ventilation. It is designed to extract moist and stale air from multiple rooms at once, these rooms include kitchens and bathrooms. A C-MEV unit provides a quiet system and more effeicnet than separate fans in each room. A C-MEV is more commonly known as a Mechanical Extraction Ventilation (MEV).

The unit is usually situated in a loft or roof space. It works by continuously extracting at a low ventilation rate. A mechanical extraction system can create energy savings as there is no need to run a lot of extractor fans in every wet room in a home. There are also beneficial over fans as they do not crate air leakage, heat loss or drafts.

Mechanical extraction is advantageous as it eliminates damp and polluted air creating a healthier and better indoor air quality.

BPC stock a range of C-MEV units from worldwide leading manufactures such as:

-      Vent Axia

-      Xpelair

-      Passivent

-      Domus

-      Duco

Centralised mechanical extract systems can be purchased singularly or in a MEV Kit that comes with required fittings depending on how many rooms the unit will service.

What is D-MEV?

D-MEV is a Decentralised Mechanical Extract System which is designed to replace conventional bathroom fans and draw out moisture laden air from wet rooms such as bathrooms and utility rooms. D-MEV systems provide a more efficient and a quieter system than separate fans.

Decentralised Mechanical Extract Ventilation systems are low energy systems, they are usually installed in a bathroom wall or ceiling and extracts continuously at a normal low rate of ventilation.

BPC stock a range of D-MEV units from worldwide leading manufactures such as:

-      Vent Axia

-      Xpelair

What is PIV?

PIV (Positive Input Ventilation) this is a wall or loft mounted unit that pushes filtered, fresh air through a property. A PIV system is a perfect solution to combat condensation in the home. The unit is normally fitted in the hallway and continually introduces a subtle, filtered air supply from the trapped heat and air from your roof void, this trapped heat is then re-distributed. Loft mounted PIV units use free solar energy generated from the natural solar gain in lofts which, in turn, maximises comfort and contributes to annual energy savings.

By eliminating condensation, a PIV system created a fresh and healthier living environment. It works by supply fresh filtered air a continuous rate throughout a property and is a very popular option in existing houses or landlord lets. In combating condensation, a PIV system reduces the risk of mould, damp and dust population which creates a range of health benefits like reducing risks of asthma and other respiratory issues.

BPC stock positive input ventilation units from leading manufacture Vent Axia. The range of units is the Pozidry unit range, the range comes in both a Pro version and a compact version. Each unit comes with and optional heater. Check out the range here.
