Description of the article Fernox Powerflow Flushing Machine MKIII 56779:



This product is the Powerflow Flushing Machine MK III from Fernox. It's a powerflushing machine which uses a targeted, powerful freshwater flow to remove sludge, scale and debris quickly and thoroughly from existing and contaminated domestic central heating systems. It is compatible for use with all Fernox Cleaners. After just one site-visit, the boiler’s optimum energy efficiency rating and overall system performance level can be restored; eliminating boiler noise and minimising fuel consumption. Supplied complete with all hoses and fittings ready to use straight out of the box. Circulation rate of up to 99l/min. Rated to 85ºC operating temperature. Reversible flow action. Integral double check valves on mains fill. 

This powerful flushing pump is ideal to make short work of cleaning boiler and radiator systems, without removing radiators. It can also double up as a descaling pump for heat exchangers. Saves time on-site. Using the Powerflow Flushing Machine MKIII at temperatures of up to 85ºC together with Fernox DS40 System Cleaner, System Neutraliser, Powerflushing Cleaner F5, or Cleaner F3, only one visit to site is required to powerflush a central heating system.

The Building Regulations for England and Wales, Part L 2010, now require a central heating system to be cleaned and inhibited chemically with every boiler change. The Fernox Powerflow Flushing Machine will add value to your business and enhance your professional image. Use it to offer a fast, professional and reliable cleaning and flushing service when replacing boilers. Many boiler manufacturers now make the warranty dependent on flushing and cleaning in accordance with Benchmark and Part L.
