印度采购需求：单间 ERV

I'm interested in learning more about the Eco Pair single room energy recovery ventilator you offer. Specifically, I'm looking for detailed specifications including its dimensions, energy efficiency ratings, and any certifications it may hold. Additionally, could you provide information on the installation process and whether any accessories or options are available? Understanding the pricing structure, including any bulk discounts, would also be helpful as we are considering placing a significant order. Any insights on lead times and shipping options would be greatly appreciated too. Looking forward to your prompt response to help us move forward with our purchasing decision!
