Frequently asked questions

Why so many air changes?

Animal waste and urine generate ammonia and moisture quickly; high air changes keep odour and humidity manageable and protect animal health.

Do runs need individual exhaust?

Larger facilities often duct exhaust registers low near each run row for the most effective odour capture.

What do I need to enter into the Kennel Ventilation Calculator?

Just 3 values: kennel area, ceiling height, air changes. Every field starts with a realistic example, so you can change one number at a time and watch the result update instantly.

How does the Kennel Ventilation Calculator work out the answer?
