Blair Air Systems offers a mechanical Zero Emission device it calls the Blair Air System. This product provides compressed air to operate pneumatic pumps, controllers, and other pneumatic devices which normally operate using methane. The mechanical motion for compressing the air is achieved by harnessing the flowing gas stream pressure, but with no combustion, consumption, or venting. By replacing the methane with compressed air, venting is eliminated, thereby resulting in a Zero Emission well site. Electricity is not required.
