Penguin filter chambers are offered in CPVC, polypropylene, and PVDF. The construction of the series C chambers contain no fragile lucite or glass. There is no metal-to-liquid contact, no springs to lose or break, and no crushed tubes. Penguin CPVC and polypropylene chambers are recommended for most acid and alkaline solutions. PVDF chambers are recommended for high temperature acids and alkalies, HF, and electroless nickel. All Series C chambers can be mounted on a common polypropylene base and manifolded together for greater capacities or space saving requirements.
