The Puma 18 S is an industrial vacuum from Depureco's medium-large power three-phase range. It has a high airflow high quality Made in Italy double-stage side channel blower in parallel that ensures a maximum continuous vacuum of 530 mBar. The vacuum breaker safety valve is installed as standard. The tangential intake with the sturdy cyclone welded inside the filter chamber guarantee excellent efficiency even with the finest dust. The material, entering tangentially, meets the cyclone and due to the friction generated, loses speed and falls directly into the container. This system is extremely useful to protect the filter from the vacuumed material. The filter is in Class M high grammage polyester (certified by BIA Berufsgenossenschaftliches Institut für Arbeitssicherheit) with a 1µ filtration efficiency. The filter can be customized to a specific application. For this vacuum cleaner, anti-static filters are available to prevent electrostatic charges, in NOMEX to withstand high temperatures (up to 250°C), Teflon coated to work with wet materials and with PTFE nanotechnology treatment to work with the most difficult dust. The PUMA 18 S industrial vacuum is equipped with a manual filter cleaning system. The filter can be shaken easily and effectively with the lever on the top of the vacuum. The vacuum can be configured with an automatic filter cleaning system on demand. Namely, there is a choice between jet pulse cleaning, electro-pneumatic piston filter shaker, or electrical filter shaker. Depureco's PUMA 18 S model is equipped with a handy and sturdy 175 L container, fitted with a release system,
