Dear Chan,
Please find attached the proposed offer. You may please incorporate / modify as shall be required and arrange onward submission to client. Please be informed that this is a very big Bag Filter with 8 fields & total about 1800 Filter bags of bag length 4800 mm.
Price wise, the difference from the earlier offer is due to use of two different quality filter bags. Earlier one was with 100 % PTFE as that was the only suitable fiber for the application.
In this case the filter bag shall be PPS (Ryton) with PTFE lamination, the best suited filter bag for Coal fired boiler application with trances of Sulphur in the flue gas.
Please write back if any other clarification / confirmation is needed
