Additional Notes

Certification and standards information for this product is not yet available. Please contact Ventex for more details.

At four inches deep, the ACL440/ACL445 is a compact acoustic louver suited for space-constrained installations where noise reduction is still required. The standard straight blade configuration provides a reliable balance of acoustic attenuation and airflow, making it a practical choice for pumping stations and portable generator enclosures where depth is limited.
