BollFilter High-Quality Filtration Systems

BollFilter Protection System – the World Leader in Filtration Systems

Built to protect your valves, pumps, bearings, nozzles etc.  from pollution, BollFilter Protection Systems reliably filters dirty fluids and feeds the cleaned substances back into the process.

BollFilter Protections Systems are manufactured by Boll & Kirch Filterbau GmbH, a renowned German manufacturing company founded in 1950. Their continuous investment in research and development has made them the world leader in liquid and gas filtration technology.

Boll & Kirch is firmly committed to the protection of the environment, which includes designing preventative measures to minimize emissions, save water and energy.

MSHS is proud to represent Boll & Kirch in the Americas and the Caribbean, offering complete units, spare parts, service and hands-on training for your existing and new BollFilter Protection Systems.

BOLL & KIRCH filters offer reliable protection from catalytic fines (cat fines) in mandated low-sulphur fuels. Cat fines are highly abrasive particles that cause engine component wear. Main and auxiliary engine manufacturers recommend Boll & Kirch 10 µm abs filtration products to prevent potential cat fine damage. No other manufacturer has installed as many 10 µm abs fuel oil filters as Boll & Kirch.
