Cattle barn fans vs poultry tunnel wall exhaust: which applies
Answer first: Cattle barn fans and poultry tunnel wall exhaust are different products on this site. Cattle barn fans are hanging or aisle box fans for cattle and dairy barns. Wall exhaust fans (box, hammer-shutter, cone) are for poultry houses, swine barns, greenhouses, and workshops — and are not cattle-barn hanging box fans.
Use this guide to pick the right product page before you email a brief. Ratings and configuration are confirmed on the written quotation.
Cattle barn fans (hanging / aisle)
From the cattle barn fans page:
- One cattle barn box fan line with blade choices: black blades, stainless blades, or full stainless.
- Use: cattle barn / dairy barn air mixing and heat relief.
- Mounting: hanging or paired aisle frames.

Typical size bands in m³/h are listed on that page to help selection. Confirm air volume, power, and bracket on the written quotation. Installation dimensions follow your site requirements.
Poultry / swine tunnel wall exhaust

- Wall-mounted negative-pressure exhaust for poultry houses, swine barns, greenhouses, and workshops.
- Three wall-exhaust types: Box, Hammer-shutter, and Cone (galvanized or FRP for cone).

FAQ
Is a cattle barn box fan the same as a poultry tunnel wall exhaust fan?
No. EcoHarvest cattle barn fans are hanging or aisle-mounted box fans for cattle and dairy barn air mixing and heat relief. Exhaust fans on the exhaust-fans page are wall-mounted negative-pressure fans for poultry houses, swine barns, greenhouses, and workshops in box, hammer-shutter, or cone styles. The exhaust page states they are not cattle-barn hanging box fans.
When should I look at cattle barn fans?
Use the cattle barn fans page when you need a blue-housing box fan for cattle or dairy barns, mounted hanging or on paired aisle frames, with black blades, stainless blades, or full stainless. Quote from barn length and width, eave height, stocking, country, voltage and frequency, mount type, and blade choice.
When should I look at poultry / swine wall exhaust?
Use the exhaust fans page when you need wall-mounted negative-pressure exhaust for poultry houses, swine barns, greenhouses, or workshops. Pick Box, Hammer-shutter, or Cone on that page. Catalogue air volumes in m³/h are listed there and confirmed on the written quotation.
Do you publish CFM tables for either line?
The cattle barn fans page lists typical size bands in m³/h to help selection; confirm ratings on the written quotation. Exhaust-fan GPF / ZHF / GKF catalogue air volumes in m³/h stay on the exhaust fans page and are confirmed on quotation. This site does not add a separate CFM column, lab static-pressure tables, or prices.
