Application areas

(5)

Construction sites may be at risk when it comes to silica, wood or other types of dust.
Construction
Dust from cutting, drilling and grinding concrete, brick and similar building materials contains crystalline silica.
Residential construction
Air cleaners are perfect for large public spaces such as airports, concert halls and public events.
Public spaces
Manage dust using high-quality professional equipment with a HEPA H13 or H14 filter and personal protective equipment.
Renovation
Handling hazardous materials is regulated and requires rigorous safety measures.
Abatement & remediation

Husqvarna Manage Dust With Confidence 16:9 (INT)

Protect yourself from dust

Construction sites are prone to dust from activities like drilling, cutting and grinding. This dust may contain crystalline silica, a hazardous substance that has been referred to as “the biggest risk to construction workers after asbestos.”*

Invisible to the human eye

Small (respirable) particles of crystalline silica can penetrate deep into the lungs.* They are so small (0.1–5.0 μm) that they might hover in the air for hours, invisible to the naked eye.

This is why it’s important to use work methods that catch dust at the source and prevent it from becoming airborne. To handle dust effectively, use high-quality professional dust control equipment with a HEPA H13 or H14 filter and personal protective equipment.

New-generation air scrubbers

Husqvarna's latest range of air scrubbers are developed with a new level of intelligence and mobility compared with the previous generation. Based on a standard roof height of 2.5 m and an air exchange rate of 10 times per hour,* the A 45 is recommended for spaces up to 45 m2 in size and the A 25 up to 25 m2 in size. Multiple units can be combined as necessary for optimal air cleaning of larger spaces.

All machines feature a colour-coded LED bar that is visible from a distance and clearly indicates the filter status. The compact and stackable design is beneficial not only for maintenance but also for transportation and handling. The units can be used as both air scrubbers and negative air machines. Two-stage filtering captures silica dust and dust from wood, metal, gypsum, and other materials. Optional active carbon and HEPA 14 filters are available.

Use our calculator to choose the correct air scrubbers setup for your specific room or location.

*According to AMV, the Swedish Work Environment Authority, an air exchange rate of 10 times per hour is recommended to sustain a safe working environment. Source: https://www.av.se

Colourful filter alerts

The multicoloured LED bar provides a straightforward indication of filter status, making it easy to monitor machine status from a distance. All models feature a sound alarm, and a red flashing light indicates when the pre-filter or filter needs to be changed.

Using light combined with sound to show status ensures that everyone nearby can easily see that the machine is running and if the filter needs to be changed. Moreover, it facilitates proactive maintenance planning to minimise downtime.

The machine can be extended to 3-stage filtering with the optional active carbon filter, which helps remove contaminants like odours, gases, and chemicals from the air.

Multiple fan speeds

The A 45 features three fan speeds for different noise-level and filtration needs. The machine’s lowest fan speed is its quietest, at 50 dB. The standard and full-flow fan speeds create a higher air exchange for faster air cleaning.

Made to move

The low weight, together with the smart and robust design, makes the air scrubber easy to handle, carry and store for transport. The innovative and stackable construction provides versatility for placement.

Filter configurations

(4)

Essential in mechanical air cleaning to protect and extend the lifetime of HEPA filters. The pre-filter is made out of PTFE material ensuring a maintained air flow.
Pre-filter (standard)
The High Efficiency Particle Air (HEPA) filter is the main filter in an air cleaner, designed to filter out the smallest respirable particles. According to US standards, a true HEPA filter has a 99.97% filtration capacity. The EU defines HEPA H13 as having a 99.95% filtration capacity.
HEPA H13 filter (standard)
Often referred to as an activated carbon filter. An optional filter that utilises carbon to capture chemicals, gases and volatile organic compounds (VOCs) like smoke.
Carbon filter (optional)
If an application requires you to only move air, you can also run the machine without any filters.
No filter
