Pulmac Systems Irritated with QS Fibre

Posted 31/7/2017

Communicating through lawyers, Pulmac Systems International of Williston, Vermont has expressed its frustrations with QS Fibre's re-entry into the marketplace following the expiration on 21 May 2017 of our non-compete obligation. They seem to fear that customers may be confused and think that they are dealing with Pulmac Systems, a company incorporated in 2012, when they in fact are dealing with QS Fibre, incorporated as Pulmac Inc in 2003. Let me set the record straight. Other than the fact that QS Fibre, was an original shareholder in Pulmac Systems before selling its shares in 2013 and terminating its business association in 2015, QS Fibre has no association whatsoever with Pulmac Systems.  In fact, QS Fibre competes with the relative newcomer. We strongly believe our products and services to be superior and we strive to bring them to the market at a better price. Unused to competition, Pulmac Systems does not appear to be handling it well. We, on the QS Fibre team, say let the market be the judge.
