The higher the MERV is, the more efficient the filter is in trapping airborne particles.) For example, a MERV 15 filter is up to 99.9 percent efficient at capturing particles from 1 to 0.3 microns, the average size of most welding fume particles. This rating is usually recommended when the air will be recirculated.

Grain Size of Silica Fume. While the particle-size distribution of silica fume may vary depending on the furnace gas exhaust temperature and the fume type, most silica fume particles are smaller than 1um, with an average diameter of approximately 0.1 um. For comparison, this presentsExhaust ductwork shall be sized in accordance with good design practice which shall include consideration of fan capacity, length of duct, number of turns and elbows, variation in size, volume, and character of materials being exhausted.

Cheyrezy 1995). Filler, sized between cement and silica fume sizes, improves the compressive strength of concrete by increasing the poured density. A mean particle size of the filler in Table 1 is 2.2 lm and the filler, as an Australian product, composed ([99%) of SiO 2 components was used. Super plasticizer, that has a specific gravity of 1 ...The FACE OPENING value is the maximal open Width x Height for your fume hood while FACE VELOCITY references the capture distance i.e. depth of the fume hood. A typical FACE VELOCITY is 100 fpm as many fume hoods are similar in depth to a standard desk. Note: For this sample calculation we are using Bel-Art – SP Scienceware fume hood catalog no. ….

National Laboratory Sales carries three-foot to fourteen-foot hoods, with every size in between. The width of the fume hood you need will be a balance between necessity and personal preference. If you plan to have multiple people working in the hood, it should be at least 5-feet wide to allow for adequate workspace. Zeidler et al.,[9] welding fume particle size is process dependent and may range from 10nm to 20lm,[9] with agglomerates in the 0.05–20lm size range according to Cena et al.[7] Literature is, however, in general agreement that the majority of welding fumes have a mass median aerodynamicdiameterof<1lm(0.20–0.50mm).[8,9]Product Details.
