Lamp Post Now Stock Full In-Line Manrose Extractor Fan Range

Lamp Post Electrical supply all electrical equipment for the power circuits of the house and office and the Internet has allowed them to build a great business, which supplies the market at prices which are well below those of the standard retail outlets. Their typical website is both informative and descriptive so that a good idea of the product can be quickly gained. Any further information can be gained by e-mail or phone. The delivery service is what the customer wants it to be, but Lamp Post Electrical prides themselves on getting the goods quickly and safely to the customer.

The extraction fan business has become more and more complex over the years as the pollution rules and regulations have become stronger and this will change still further in the next few years as environmental and social conditions become stricter. The rules on extraction fans for the bathroom and washroom areas have always been strict because of the danger of water and electricity mixing and passing electrical currents to earth. The introduction of the 17th edition RCD controlled circuits has helped matters, but most installations still use off site extractor pumps to get rid of the unwanted steam and smells.

Lamp Post Electrical have supplied the Manrose CFD200T in line extractor fan for some time and it is a very reliable piece of equipment. The pump works on a typical 4 inch diameter extraction tube that connects to the waste exit of the bathroom to the extraction fan itself. The power of the extractor fan is such that it extracts some 85 cubic metres per hour very quietly and continuously. The fan is fitted in lime and into the line and extraction is not a problem as it will deal with all the typical problems that bathroom extractor fans may have during their normal operation. It should clear away all steam developed by the shower or the bath and leave the room dry, it will also remove obnoxious smells.

Lamp Post Electrical supply all the fittings and fixtures for the operation and the only real problem is where to fix the extractor fan into its final position as this obviously needs to be outside the bathroom. It can be fitted below the floor or above the ceiling but there will be a need for a suitably sized space and also the requirements in the case of an emergency so that future access may be possible to repair or replace easily. All that then remains is a suitable access for the extracted gases to be passed outside of the building through a tube and grill. If there are no suitable access routes then there are some extractor fans which can work in the bathroom or wash room environment without the need for the ultimate protection but these must be mounted so that they cannot be reached when standing in the bath or shower.
