The cassette can be installed horizontally or vertically in the duct. It should be remembered that in the upright position the air flow is directed downwards (to ensure the correct positioning of the bags). The recommended maximum pressure drop for class F5 filters is 200 Pa, for F7 – 250 Pa, respectively. The cassettes are equipped with pressure gauges to measure the pressure drop.
