ABS (Acrylonitrile-butadiene-styrene) vs Metal Body Construction
All Drainvac unit bodys is made of new 6 mm Injection moulded ABS/polyethylene composite material. ABS is an enhancement to polystyrene made by adding a small amount of styrene-butadiene rubber for better high impact resistance and acrylonitrile for hardening to the styrene before it is polymerized. This allows it to flex under impact while still being rigid enough to keep the required shape. It is dent proof, corrosion proof, rust proof, scratch proof, with vibration free operation and is virtually indestructible. New 21st century material for years of durability.
ABS is recognized by all leading manufacturers of central vacuum cleaners for its durability and superiority.The use of this material in central vacuum units also greatly helps reduce the decibel level of a unit, making for a quieter operation.
ABS Body Construction
The types of materials used to construct the external structure and internal parts of a vacuum cleaner play a major role in the length of its life span as well as the extent of its maintenance expenses. Typically, vacuum cleaners are made of a combination of metals and various synthetic plastics. With the development of the Plastics Industry, many parts which were once metal are now made of much lighter and often stronger plastics. While reducing the production costs considerably, this change over has also made vacuum cleaners much lighter and easier to use. The key to durability is often in the excellence of design as well as the types of plastics used for various parts.
Metal Body Construction
Prior to the early 1960's, canister vacuum cleaners were primarily constructed of stamped steel cases. Many central vacuum companies still use metal as a sign of durability and strength. Metal canisters tend to be much heavier and more difficult to deal with. The vibration caused by the metal design will increase the decibel level and make the vacuum unit operate louder. The metal material may rust over time causing problems with hinges and latches. Metal material may chip over time and is NOT dent proof, rust proof and erosion proof.
