Please pass the comments below to Therec. I knew that some has been told to them and they are during prepare official quotation.
Anyway if any items repeated ,it is just good for reminder. This is from Tod and I add mine in blue for the pre-lim quotation review.
1. Does not look to be a full packaged blower with enclosure but not entirely clear as the descriptions don't contain much detail. No filter pressure indicator or temperature gauge included. Also no indication of filter efficiency or if includes food grade oil. Not clear but assume the oil can contaminate the process air if a seal leaks.
2. No detail on motor if high efficiency, the belt drive details, blower speed/percent of full speed etc.
3. We did not request vibration isolation but should this be included? Can Therec comment? Believe if a full packaged blower with enclosure these are included.
4. We do not need the 1 baroption for BL57120/BL57170. Final operating pressure will be confirmed later if we need more. Please use 0.69 Barg for current value.
5. Other factory we used blowback blower (BL57102/BL57152) is sized at 7 psig but the pressure relief is sized at 13 psig. Would need the blower motor to reach 13 psig or overload before relief valve operates. Again will confirm this when need to award. Please size as per current information we show here.
6. BL61101 shows a 10" check valve and 8" flexible. Not clear how this fits since the blower discharge is 6" according to the internet. Also our pipe is 6".
