JENNCHEM offers a complete range of rated and non-rated ventilation products and services including design and supply through to contract installation. 50 psi final seals and 20 psi longwall seals can be installed underground and pumped from the surface using the same equipment that is used for pumpable cribs. This has the operational advantage of maximising the equipment and personnel utilisation on site and minimising contract and worksite management.

In addition to seals, a full range of stoppings, doors, overcasts etc. can also be provided. All rated devices are certified by JENNCHEM affiliate company Keystone Mining Services (USA) and RPEQ Certifiers (QLD).
