The Original Compressor for Butane and Propane Solvent Recovery

Look behind the iconic black paint and skull logo on many solvent-recovery systems and you will find a blue Blackmer® LB082EC Series Reciprocating Gas Compressor. Used throughout the botanical-extraction industry, the first-to-market, with hundreds of installations, LB082EC Reciprocating Gas Compressor is the original and first choice in compressors for botanical extraction.

The UL-listed LB082EC Reciprocating Gas Compressor can play a vital role in every botanical plant oil-extraction system, extracting butane-propane solvent from material columns while producing a closed-loop system in which the butane-propane solvent can be reused in future extraction activities.

Botanical Oil Extraction Process

The LB082EC Botanical Extraction Compressor is the smallest model of LB Series Compressors and is capable of achieving a vapor-recovery flow rate necessary to facilitate the butane-recovery process. The LB082EC Botanical Extraction Compressor features double seals that have passed various leakage tests, as well as a pressurized oil-pump circuit on the heavy-duty crankcase – which is coated with a special epoxy that protects the interior – that forces oil onto the unit’s bearings, wrist pins and connecting rods. Other features of the Blackmer LB082EC Botanical Extraction Compressor include:

  • Heavy-Duty Pistons – One-piece construction that is stronger and simpler than competitive multi-piece designs
  • High-Efficiency Valves – Corrosion-resistant stainless-steel discs and springs that provide superior sealing
  • High-Pressure Head and Cylinder O-Rings – Eliminate leakage and maintenance problems
  • Self-Adjusting Piston-Rod Seals – Prevent crankcase oil contamination and cylinder blow-by
  • Pressure-Assisted Piston Rings – Provide maximum efficiency with minimal friction wear
  • Wear-Resistant Crosshead Assemblies – Designed for maximum lubrication and wear resistance
  • 2-hp Motor – More energy efficient and less wasteful than the competitor model with a 3-hp motor

All of these features combine to make the LB082EC Botanical Extraction Compressor an ideal solution for continuous-duty botanical oil-extraction applications with 2-4 vapor-recovery cycles over an eight-hour period.

Since you are already using butane, considered by many to be the purest solvent in botanical-oil extraction, it only makes sense to trust the original extraction compressor, the Blackmer LB082EC, for your botanical-oil extraction activities.
