What is a RESPA cab air quality system?
A Sy-Klone RESPA cab air quality system will provide clean filtered air for your machine cabs HVAC system (Heating, Ventilation, Air Conditioning). Equipped with a high grade HEPA filter and powered pre-cleaner the RESPA-CF and new RESPA-CF2 systems protect the machine operator from dangerous dust and particulate. The RESPA cab air quality system provides a much higher level of protection from harmful dust and particulate than most factory standard cab filter systems.
Why not just fit a replacement standard HEPA panel filter?
A HEPA filter will remove dust and particulate down to 0.3 micron in particle size. This includes substances such as Asbestos, respirable silica, diesel particulate, and even bacteria spores. Without suitable pre-cleaning a small HEPA filter will clog very quickly and in a poorly sealed cab the HVAC unit will start to draw unfiltered air in to the cab. This effectively makes the HEPA filter next to useless as the machine operator is still exposed to unfiltered air. There is also nothing to warn the operator when the filter becomes blocked.
The 4 Components of a RESPA Cab Air Quality System Installation
A RESPA cab air quality system installed by Desert Engineering is more than just a replacement filter. It is in fact a 4 stage solution:
1 – Powered Pre-Cleaner
The first stage of the RESPA system is a powerful pre-cleaner that protects the HEPA filter, vastly extending the life of the filter.
Air is drawn into the RESPA unit and forced into a Vortex, rotating around the cylindrical housing as it travels along the unit. This forces dust and particulate to the outside of the RESPA unit away from the HEPA filter where they are harmlessly ejected from the unit. This powerful pre-cleaning system can eject more than 90% of the dirt and debris before it gets to the HEPA filter.
2 – HEPA Filter
The HEPA filter used in the RESPA system is a high grade cylindrical HEPA (H13) filter. The filter itself has a large surface area and is sealed at both ends to prevent any dust or debris from bypassing the filter media. A HEPA filter is a requirement for HSE AG7 and QY11 cab air quality guidelines and will remove dust and debris down to 0.3 micron in size. This protects the machine operator from harmful materials such as Asbestos, Respirable Silica and even bacteria spores.
3 – Cab Sealing
One of the most important parts of a cab air quality system installation is sealing the cab to an appropriate level. Without sealing the cab sufficiently it is not possible to achieve a suitable positive cab pressure for a safe working environment. Some machines claim to have a sealed cab but with the airflow restriction of a HEPA filter and where positive cab pressures of 50Pa or 100Pa are required most cabs fall a long way short. Desert Engineering provide a thorough cab sealing service as part of a full RESPA installation which can often include the complete removal of the cab in order to properly seal the frame and floor.
4 – Pressure Monitor
The final stage of a cab air quality system installation is the cab pressure monitor. This important device constantly monitors the pressure level inside the cab and warns the operator if the pressure drops below the recommended safe level. It will also warn the operator if any doors or windows have been left open as this will result in zero positive pressure. As the HEPA filter eventually becomes clogged the cab pressure will gradually drop. The pressure monitor enables the operator to know when to replace the HEPA filter.
