Requirements for a Safe Woodshop Dust Collection System | Air Associates

Design a ventilation ventilatikn for the building shown below. The building is a small workshop used for general vventilation fabrication and welding. No welding booths are installed. If wpod building gets too warm the door may be opened pddf free cooling. DATA: Building dimensions : Roof ridge height is 7. The air change rate for mechanical ventilation is to be 6 air changes per hour. What areas need ventilation? Answer: The total area of the workshop.

The contaminants are welding fumes and heat. What type of system should be used, supply, extract or balanced? Answer: Extract. Are there any alternative systems to consider? Answer: No, supply air is not wood workshop ventilation pdf. Is air conditioning necessary in the building? Answer: No, external door to be opened.

Where should the psf s and plant be installed? Answer: On the roof. What type of fan s and plant should be used? Answer: Roof mounted units with weatherproof cowl. Anti-backdraught shutters on each fan. Woood ductwork. Is a separate heating system necessary? Answer: No, not for extract only. What type of control system should be used? Answer: Variable speed fan s for a flexible system. What type of air distribution system should be used, upward or downward?

Wood workshop ventilation pdf Upward for extract systems, with duct mounted extract grilles. Have I considered what will happen in the event of a fire in the building? Answer: The fans could remove smoke in the event of a fire. Have I wood workshop ventilation pdf the noise from fans?

Answer: In a workshop, fan noise is not a problem. Calculate Ventilation rates. Draw scale wood workshop ventilation pdf drawing: Position fan s. Lay out ductwork. Lay out grilles and diffusers. Indicate flow rates on drawing. Size ductwork 5. Size wood workshop ventilation pdf 6. Size grilles and diffusers. There is no explicit rate given for Factories and warehouses or Industrial ventilation due to wlrkshop variations Workshop Woodworking Machinery Pdf in building design and usage.

The Wood Workshop Gloucestershire Pdf rate for this example is given in the question as 6 air changes per hour. Three extract roof units are used so each will remove 1. The resistance to air flow is negligible since there is no ductwork or grilles connected to the fans. It is a good idea to look at several types of extract unit to ascertain the best option for the job.

A typical unit is shown below. Wood workshop ventilation pdf curves show the pressure developed by a fan at a given flow rate. The operating point of the system is marked as a point on the curve. In the absence of duct resistance data we can look at typical fans for the job. From the wlod table, the propeller wofkshop fan and the axial flow fan produce 32Pa and 55 Pa pressure which is sufficient for the proposed system.

The noise output from both fans is similar. I would choose the DSP propeller type unit since a speed controller is available.

The ductwork resistance can be calculated later to ascertain an accurate fan size. Open navigation menu. Close suggestions Search Search. User Settings. Skip carousel. Carousel Previous.
