Illuminated Vacuum Table, high or low-pressure
The Vacuum Table surface is the size of an Imperial sheet of paper with a one-inch buffer added to each dimension (31 inches x 23 inches). Supplied with two vacuum pumps, an FPZ lowpressure regenerative blower of light construction, which creates a maximum vacuum of 275 millibars that will pass a maximum 400 litres per minute. The second is a Gast 1023 high-pressure oil free vane pump, providing up to 800 millibars moving a maximum of 200 litres per minute. The FPZ pump gives the initial seal and vacuum. If more vacuum is needed the Gast is turned on automatically. They work in conjunction up to a vacuum level of approximately 220 millibars, at which point the Gast takes over with the ability of lifting the vacuum to 800 or 850 millibars. Once the vacuum is over 220 millibars the FPZ pump is automatically turned off by a vacuum switch. Each pump is fitted with a non-return valve to ensure that one pump does not draw air through the other.
The work surface is made of sintered polyethylene which has a slight resistance to the passage of air, enough to distribute the level of vacuum evenly over the whole surface. The material is washable.
The sintered polyethylene is carried on a PVC insert which is drilled and grooved, again, to ensure an even vacuum over the whole surface. Both are carried in a polypropylene tray.
The table also features an integral lightbox which is fitted beneath the vacuum table emitting 55W of light with a colour temperature of 4000 degrees Kelvin. Two small fans keep the compartment cool.
A small area, high pressure machine ideal for the removal of pressure sensitive tape adhesive and for small stain removal. The suction point is let into the centre of a stainless steel surface of 770mm x 470mm (30" x 18"). The vacuum surface measures 100mm x 100mm and is of sintered polyethylene. If required the whole stainless steel worktop can be lifted from the machine to stand in a fume cupboard or on a larger work surface. The vacuum pump will create a vacuum of up to 850 millibars or 85% of a pure vacuum. The pump is a Gast 1023 oil free, rotary vane pump, 0.5 H.P. Single phase.
As with the larger Buchanan Vacuum table the ‘Suction Point’ incorporates an integral light box to assist in making an even dyed pulp infill or for accurate repairs.
Alan Buchanan Cedar Wood Humidification System
The cedar wood humidifying box is a closed chamber sitting on a non-porous surface with cedar wood sides and a polycarbonate lid. The box itself is formed by two ŒL shaped pieces for ease of handling and storage.
Cedar wood has useful properties; it's an insect repellent, suppresses mould and is highly porous. A reservoir of water is provided inside the box by dampened capillary matting or fleece.
The object to be humidified can be placed on a screen over the reservoir or on a breathing membrane such as GoreTexË or one used in the building trade to go beneath the tiles to permit water vapour to escape.The rate of humidification is slow, gentle and all-pervading because the cedar wood absorbs excess vapour.
Control of the rate of humidification is achieved by the amount of water sprayed onto the reservoir. The more water that is sprayed or dampening the dear wood walls, the quicker the humidification. For very slow humidification the reservoir can be omitted and the external surface of the cedar wood can be repeatedly sprayed with water which will pass through the wall and will be absorbed by the object within the chamber.
