As noted earlier, when compared with the standard downdraft spray paint booth, you won’t be compelled to undertake any concrete work to install exhaust pits and tunnels. Neither will you be forced to install a raised steel basement in your paint facility. All this without in any way sacrificing on the overall quality of your unit’s finishes and overspray and contaminants control capabilities. This means you will be able to save much on the upfront costs of constructing a side downdraft paint booth in your shop.
On the downside, this sort of unit necessitates a bigger footprint since it requires more exhaust fans, ductwork and roof penetration than most other alternatives. Also, the exhaust plenums which are situated on the lower side walls increase the unit’s overall width. When compared to the cross-flow spray booth, the operational costs of using a side downdraft unit are a bit higher. This may be attributed to the latter’s whole ceiling filtration system.
