Jennchem offers a complete range of rated and non-rated ventilation products and services including design and supply through to contract installation. 20 psi longwall seals, 50 psi and 120 psi final seals, can be installed underground and pumped from the surface using the same equipment 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 Jennmar Engineering Services (USA) and RPEQ Certifiers (QLD).
