I am looking to purchase laminar flow air diffusers equipped with stainless steel grille boxes and high-efficiency particulate air (HEPA) filters. Specifically, I need 12 pieces of one size and 6 pieces of another size. It's important that the HEPA filters achieve a filtration efficiency of 99.99%. Could you please provide a detailed quotation for each of the specified products? I'd appreciate it if you could break down the pricing, including any additional costs or potential bulk discounts. This will help in making an informed decision for our procurement process. Looking forward to your prompt response. Thank you!
