Note for Bidders A manufacturer of this air blower should be a company regularly engaged in design & manufacture of blower of required size, speed & pressure range and should be capable of designing & fabricating the blower in accordance with the requirements of the latest available edition of all relevant safety codes, at the time of fabrication. The manufacturer should enclose the list of clients in to whom he has supplied blower of similar size, speed & pressure range along with the contact details (name of contact person, phone number, email address etc.). The manufacturer must submit a detailed quality assurance programme (QAP) indicating quality checks applicable at various stages of fabrication starting from raw material to final testing. In case of order placement a detailed QAP with necessary drawings, documentation & calculations for obtaining necessary approval shall have to be submitted, before taking up the blower fabrication. The manufacturer shall complete the questionnaire as per Annexure-A and submit it along with their offer. Without the completed questionnaire the offer is liable to be rejected. A comparative statement of technical specification of the blower intended versus the blower being offered as per Annexure-B, must be furnished by manufacturers, without this comparative statement the offer is liable to be rejected. The supplier shall submit the detailed bill of material along with the technical offer. In the event of placement of order, the supplier has to submit 2 sets of detailed assembly & part drawings along with specifications.
