Working in the recycled, environmentally friendly green world has its challenges. When it comes to the recycling of some chemicals, odours and fumes can be a hazard to the employees.
Recently, a Komatsu client had Crisp Airgineering’s POD-50 systems installed onto their new Komatsu excavators.
The POD-50 manages particulates, odour and dust and can deliver clean air to the workplace / workspace at 50l/s, giving positive pressurization through a four-stage filtration system, which includes a hospital-grade high-efficiency particulate arrestance (HEPA) filter and an activated carbon filter as part of the clean air process.
The airflow rate can be reduced to assist with the air-conditioning load should the cabin be reasonably well sealed. A 20% airflow above cabin cubic volume gives positive pressure in most cases.
The POD-50 is a rooftop-mounted unit that requires an adaptor plate to marry between the POD-50 mounts and the vehicle roof mounts without degrading the integrity of the ROP / FOP.
In some cases, rare earth magnets with a high attraction rate are used to assist with the fitment. Ducting is used to run from the POD-50 to the evaporator’s air intake on the vehicle. The system is completely sealed to assure integrity. A negative ion option is available to assist with air freshness and CO2 levels in the cabin.
