A system that needs super long hose lengths for light weight waste requires a number of considerations.

• Can the system be used for anything else if you want to swap to heavy or wet waste
• Will the power source be consistant and reliable
• Is the system simple to maintain and provide long trouble free running

Deciding on the right system for your requirements will be crucial if you plan to have a industrial vacuum system that can be used for many different tasks. There are three main choices. Positive displacement blowers, air powered vacuums or electric fans. The power source for Vacteck Vacuums "Vac n Sack" insulation and dust vacuum was decided on after tests on all three styles of power source. The Positive displacement blower was the standout. The air powered vacuum had the grunt and power but fell short when long suction hoses in excess of 20 metres were required unless a large air compressor was available. The electric fan style even when doubled up or tripled failed to impress. It can generate air flow which is fine for light waste but next to useless for anything heavier. Additionally if any dust passes through the filtration into the motor then it can be destroyed and require replacement.

The initial setup of a fan system is less expensive however once the fans require replacement as they cannot run for the same lengths continuously like a positive blower, then the costs will start to match up and you have far less perfomance. Choosing a fan powered system will lock you and your organisation into a certain style of industrial cleanup. Light waste with no ability to lift heavy waste or wet sludge and slurry. IF you are serious about a vacuum machine with grunt then the PD blower is the answer.

Independant power source 50% vacuum Ultra high air flow No airflow slippage Dual lubrication chambers Lifts all heavy waste Does not require electricity Designed for long continuous running Will operate with external attachments (Cyclones for heavy waste)	Requires customers electricity If hooked to a generator this can be expensive and unreliable Multiple fans need expensive generator Multiple fans can blow customers household electricty Very low vacuum Cannot lift heavy waste Motors heat very quickly Motors can be destroyed if waste passes through into fan blades Not enough power for external attachments (Cyclones for heavy waste)
