南非采购需求：DM系列

I'm looking to get a quote for a couple of your industrial fans, specifically two units of your larger size and two of the smaller one. Could you please provide me with the pricing, lead times, and any available options or features that come with these models? Additionally, if you have any current promotions or bulk order discounts, that would be great to know as well. I'm interested in understanding the best shipping options and estimated delivery times to my location. Your prompt response would be appreciated as I'm keen to move forward with this purchase soon!
