Dust extraction is an increasingly important requirement when power tools are in operation and the new Makita 447M dust extraction unit meets the highest levels of the performance embodied in the EN 60335-2-69 standard, which is a pan-European prescription. Class M regulations require the dust extraction machine to be able to remove dust from the work area efficiently so that there is no pollution greater than 0.1milligrams per cubic metre of air.

The OEL value - Occupational Exposure Limit - is the rating that denotes the dust hazard maximum concentration in the working atmosphere. The lower the OEL value the more hazardous is the dust. Dust class M is a Medium hazardous rating, which determines the construction and performance of the dust extraction unit.

Wood dust is the most common hazard in dust class M and the legal requirement to clean away this hazardous pollutant requires by law, the performance of the Makita 447M extraction unit. Other pollutants in this class are copper used in wires, roofing, heating tubes and metal fittings. Platinum in switchgear and exhausts catalysts, nickel in the steel industry, manganese in rail lines and Borax in china production are all class M hazards.

The new Makita 447M has a maximum airflow volume of 127 cubic feet per minute and has a mandatory airflow sensor fitted which provides an audible warning to the operator if the airflow velocity reduces below the required minimum 20 metres per second standard, if the filter is not performing adequately.

The 447M dust extractor has the required extra fine PET-fleece filter with a maximum permeability of 0.1%. This means that the lower the degree of permeability of the filter process the cleaner the air that is exhausted from the vacuum unit. This Makita dust extractor uses the “x-tremeClean” automatic filter cleaning system, which uses valves to alter the air route through the filter to clean each half of the filter when the machine is switched on and during use. The PET-fleece long lasting filter cartridge is washable for maximum performance.

Powered by either 110v or 240v mains motors with 1,000 input wattage and output power of 2,750w and 3,000watts respectively, this extractor can be coupled to power tools so that when the tool is switched on the extractor automatically starts with the soft-start low-torque system. The Makita 447M weighs 16kg, has a tank capacity of 45-litres, ergonomic handles and robust castors for easy movement. A comprehensive range of accessories, brush heads, connectors and nozzles make this versatile dust extraction plant also serve as a powerful industrial vacuum.
