印度采购需求：DM系列

I'm looking to place an order for HVLS fans and would appreciate some details on your available options. Specifically, I'm interested in large diameter fans that can efficiently circulate air in expansive spaces. Could you provide info on the specs, including dimensions, power consumption, and any additional features? Also, it would be great to know about pricing, lead times, and any bulk purchase discounts you might offer. I'm keen on ensuring the fans meet our quality and performance needs, so any data sheets or case studies would be super helpful as well. Looking forward to your prompt response!
