In both school environments and industrial premises, airborne particles can affect the working environment. In craft rooms, textile dust, fibres and small particles from fabric, yarn and the processing of materials are often produced. In industrial premises, similar problems can arise from, for example, dust, smoke, spores or other fine particles that are dispersed throughout the premises. Even when local exhaust ventilation and general ventilation are used, a certain amount of particles may remain in the ambient air. Therefore, air purifiers can be an important addition to creating a cleaner and more controlled indoor environment.
A complement to ventilation and local exhaust ventilation
An air purifier is no substitute for properly sized ventilation or localised extraction. However, it can help to reduce the levels of particles that have already spread throughout the room. This is particularly relevant in premises where several people work at the same time, where materials are handled on a regular basis, or where airborne microparticles may remain in the air for extended periods.
XAB’s air purifiers are designed to remove light airborne dust and can be used in environments such as schools, bakeries, laundries and industrial settings. The units are intended to complement basic ventilation and any localised extraction systems.
Air purification in craft rooms
Air quality is important in craft rooms, as pupils and teachers often spend long periods of time in these rooms. Textile fibres, dust from materials and small particles can be released when fabric is cut, handled, sewn or processed. Although these particles are not always clearly visible, they can contribute to a poor indoor environment.
A discreetly installed air purifier can therefore be a practical aid in a school’s health and safety efforts. The RENAIR XRA-2000 and XRA-2000EC are designed to blend into a variety of environments and can be mounted on the ceiling, wall or in a suspended ceiling frame using special brackets. This makes them suitable for premises where floor space needs to be kept clear and where installation should not disrupt teaching.
Air purification in industrial premises
In industrial premises, the air quality challenges are often more severe and varied. Here, air purifiers can be used to reduce particles from, for example, machining, material handling, packaging, smoke or fine dust. RENAIR models have a standard air flow of 1780–1960 m³/h at full speed and a maximum free-blowing air flow of 2260 m³/h, making them suitable for larger workspaces where air circulation is essential.
Filters, noise level and operation
The choice of filter should be tailored to the specific contaminants present in the workplace. Various filter options are available for the XRA-2000 and XRA-2000EC, such as carbon filters and HEPA filters. HEPA filters may be appropriate where higher separation of fine particles is required, whilst carbon filters may be relevant for certain odour or gas-related problems.
Noise levels are also an important factor, particularly in school environments. Both models are stated to produce 56 dB at full speed and 34 dB at minimum speed. The XRA-2000EC also features EC fans which, according to the product page, provide a more even airflow, lower noise levels and approximately 70 per cent lower energy consumption than traditional fans.
Part of a well-designed indoor environment
Air purifiers for craft rooms and industrial premises should be viewed as part of a comprehensive solution. The desired effect is only achieved when air purifier combined with effective ventilation, correct positioning, appropriate filters and regular maintenance. When correctly sized, air purifiers can help reduce particle levels, ensure cleaner premises and create better conditions for a safe and sustainable working environment.
