The molstic-L provides a connector input for quick and easy connection to a gas supply. There is also a 2 micron (0.5 micron for low flow) filter that protects the downstream components. An adjustable regulator protects the molbox transducers from accidental overpressure. Single channel or dual channel molstics are available for either a single molbloc, or for two to be mounted simultaneously. There are various options for low, mid, and high flow, depending on your needs.
