Multi-Function Suction Tables

These Suction Tables offer a range of versatile, controllable and interlinked features. They are used typically by fine art conservators for treatments to paintings on textile supports and by textile specialists for a large range of materials.

They may also be used for paper and other sheet materials, please contact us to discuss your requirements.

    The hand ground perforated work surface is mounted on a sturdy powder-coated box steel frame with lockable castors. An inclined instrument panel, housing the control components, is situated on one of the long sides (or can also be sited at one end if required)


    Suction, the principal function of the table is to hold objects safely and securely in place with air pressure while they are being treated. This is achieved with a high volume, direct drive dual impeller exhauster. Motor speed is variable and electronically controlled with a finger operated dial. The digital readout is in Millibar steps. Expelled air can be vented externally, or through an optional carbon filter.

    Heated work surface is achieved with the proven Willard heating system, which provides a highly reliable, accurate and above all even temperature across the entire table work surface with a separate temperature setting dial and a temperature readout on the control panel.

    Edge heating is an indispensable feature fitted to all Multi-Function Tables. Perimeter mounted elements maintain an even temperature across the working area from the centre to the edges of an object to ensure even bonding and minimum distortion. A separate temperature setting dial is mounted on the control panel and all heating circuits are controlled by accurate, fast reacting electronic thermostats with sensors situated: immediately below the perforated work surface.


    DUCT HEATING Fitted to all models featuring humidification, this essential system prevents condensation of water within the ductwork. insulated heating circuits warm the flow of re-circulated, moisture laden air to ensure an evenly controlled supply. This feature also helps dry the table internally after use.

    FULL AIR CIRCULATION The unique Willard multi-layered ducting system allows a consistent supply of re-circulated air to the object, whilst maintaining the main holding (suction) pressure. Rows of closely spaced ducting directly below the work surface have positive and negative pressures which conduct conditioned air through and along the object in contact with the surface. A dedicated high volume circulation blower feeds the system, reversing at intervals to ensure even distribution of conditioned air. The air circulation system can also be used to dry an object in place on the table using ambient air.

    HUMIDIFICATION A Willard high capacity evaporative humidifier supplies a stream of moistened air at a selected % RH for even, controlled relaxation of textiles and textile linings. This facility utilises custom made sensors situated directly below the perforated work surface in the airflow around the object. A dial operated control and digital readout (%R.H.) are fitted to the control panel.

    DE-HUMIDIFICATION Circulated air is passed through a custom made de-humidification plant, removing excess moisture to achieve controlled drying of the object from below. Condensate collection and contained water drainage are incorporated into the system.

    REFRIGERATIVE COOLING For enhanced cooling, re-circulated air is directed over the refrigerated part of the de-humidifier. This is especially useful when the Multi-Function Table is used in warm environments.

    BY-PASS COOLING Ambient air is drawn by the suction exhauster beneath the work surface to dissipate heat. The air is then exhausted into the room or vented externally. De-humidified or cooled air may be introduced from an external source.

    HEIGHT ADJUSTMENT Powered adjustment is available on the smaller tables, using synchronised legs, which allow a typical 200mm (8 inch) of height adjustment, this assists in circumstances where many conservators within a mixed height workforce may be required to operate the table.

    CARBON FILTER An activated carbon filter can either be incorporated within the table exhaust system or supplied as a free standing unit connected in line directly into the exhaust outlet on the table, this is particularly useful where external venting is not possible

    TABLE SIZES, All tables are built to order and can be produced in a range of sizes from the smallest 1200mm x 1800mm (4ft x 6ft) to the larger size of 2500mm x 4000mm (8ft x 13ft) or even larger, if required.
