The Vac n Sack system comes in many different power ratios and sizes depending on your job requirements and the city that you would be doing the vacuuming. In Sydney or Melbourne for example there is a very high level of lead dust and carbon inside roof cavities. This presents many problems, not least being that the EPA (Environmental Protection Agency) require vacuum systems that recover roof insulation to be enviromentally friendly and not release dangerous dusts and exhaust fumes into the air. Vacteck Vacuums  has produced this range of vacuum systems with up to 4 stages of filtration and the last stage on the exhaust being a fully fledged HEPA filter.

The second problem with recoverinmg old roof insulation and dust is that the filters will block up and system will not work if standard cartridge and unsuitable filters are used. The Vac n Sack system has been tested extensively and with the backing of major filtration companies and experts like FMS and Donaldson Torit, Vacteck Vacuums has produced a high powered and efficient vacuum system for the messiest of jobs.
