Capitis Exploration has been operating NCA helicopter portable air compressors on our seismic drilling programs for over 15 years. NCA compressors are perfectly suited for shot hole drilling with 3” DTH hammers. They have excellent portability with a Bell 212 or other medium size helicopter, compressors can also be moved in two lifts by a smaller helicopter. Set up is quick and easy on site and they are easy to operate and maintain. We have deployed over 40 units over the years on many projects all over the globe. We have always found NCA after sales technical and spare parts support as excellent.
