Airtight + Gastight

Doors with Extremely Low or Zero Leakage Rates

In addition to our blast and pressure resistant doors, Overly can also provide air- and gas- tight doors that are designed for applications where extremely low or zero leakage rates are a must despite relatively high differential pressures and/or exposure to extreme environmental conditions.

These doors can be equipped with a variety of gasketing materials and configurations specifically designed to meet project requirements. Email Overly's engineering design group your specific project requirements to review for possible product availability. Contact us today.
