We have three units that are suitable for hospitals and medical environments:
- The Blast – perfect for large spaces and wards
- The Blast Mini – half the size of the Blast with versatility for wall or ceiling mounting
- The SA600 – ideal for smaller clinical rooms

Added extras

A grille / plenum can be attached to the Blast and Blast Mini air cleaners to allow a full fresh air connection to the unit.
With a spigot of 150mm, a flexible hose can be connected and run outside either an open window or a window vent.
This vent is easily removable so the unit can function as a standard portable air cleaner.
Wall mounting
For illustrative purposes, the images below show how the Blast Mini can be wall mounted. Click here for more details on wall mounting.


Ceiling mounting
The Blast Mini was used as both as standalone purifiers for BBC World Services, and installed in the ceiling, wiring the switch into the wall.



Our approach to healthcare
Our commercial air cleaners are designed to deliver exceptional performance, unobtrusive operation, low noise and unbeatable value. Our air cleaners are on wheels for manoeuvrability and mechanical, which means no interference with essential electromagnetic medical devices and automatic start-up (at last speed) after a power failure.
As a plug and play with no electronics, it is simple to use and maintain with no training necessary. Such simplicity means reduced costs for ‘on the ground’ support, although we will be there for the delivery of the units and to advise on set-up.
Noise matters - we have seen air cleaners switched off in hospitals, even with staff training and posters asking for these not to be switched off. An air cleaner should run at the speed capable of providing enough clean air for that space at noise levels conducive to working/recovering. If turned down lower (or worse, turned off), an air cleaner is no longer effective. By making noise as essential as airflow, Smart Air delivers the quietest, high-airflow, commercial air cleaners in the market today.
Support and maintenance
Self-service support
Changing the filter takes less than 5 minutes with no tools required.
The illustration to the right is our taller Blast unit but the process is the same: lift off the top panel, then the front panel, change the filter, drop the front panel and place the top panel back on.
The simplicity of the design makes it an easy option for the Estates team to manage.


Warranty
The warranty is up to 3 years for motor faults. The Smart Air purifiers are mechanical and not having electronics allows us to keep the price down and reduce the number of faults, most of which tend to be with electronics.
The motors in both the Blast and Blast Mini are equipped with a failsafe design, to prevent overheating. That means you can run your Blast and Blast Mini continuously, without any issues. However, to prolong the lifespan of the motors, we advise that you occasionally turn off your motor, to allow it to cool. We generally recommend turning your purifier off after 12 hours to provide the longest lifespan for the motor
Availability and lead times
Where units are in stock, it can be ready to ship within 5 days. If we need to order stock in, we can deliver it within 3 months.
Environmentally friendly
We upgraded our packaging to ensure it is 99% plastic-free and we designed our Blast units with high-quality steel rather than plastic.

At the end of 2021, we launched the latest version of the Blast units and switched to using cardboard-framed HEPA filters. This not only reduced the carbon-footprint our filters, it also provided us with the following benefits:
- Lighter weight results in reduced transport costs
- The filter effectiveness exceeds that of the old aluminium-frame filters
