By integrating premium pneumatic engineering with heavy-duty system components, their solutions safeguard processing environments from the operational liabilities of dust accumulation, protecting equipment longevity and maximizing plant floor productivity.

The core design philosophy of Legends Equipment centers on absolute system reliability and specialized regulatory compliance. Rather than deploying undersized, off-the-shelf commercial hardware that succumbs to premature filter blinding or mechanical wear, Legends balances air-to-cloth ratios, line velocities, and material characteristics to construct optimized pneumatic conveyance networks. From configuring massive multi-point header pipes stretching across multi-level manufacturing plants to selecting specific abrasion-resistant tubing and fittings, every configuration is custom-built to deliver continuous static pressure and reliable volumetric airflow at every extraction point simultaneously.

Trotter Equipment Company maintains a long-standing professional partnership with Legends Equipment across Ohio, Indiana, Kentucky, and West Virginia. Our regional application engineers combine Legends’ specialized central vacuum engineering and technical laboratory testing assets with Trotter’s localized field experience in industrial process infrastructure. Together, we work alongside processing plants, grain elevators, and chemical facilities to analyze raw material dust dynamics, design code-compliant extraction layouts, integrate centralized control platforms, and provide lifelong aftermarket technical field service and wear component support.

Legends Central Vacuum & Source Capture Technologies

Legends Equipment supplies complete, fully integrated vacuum networks comprising heavy-duty exhauster units, multi-stage primary filter separators, static-dissipative conveying lines, and ergonomic operators’ utility tool packages tailored to handle demanding powder and granular matrices.

Industrial Vacuum Producers & Exhausters

The mechanical driving force behind every Legends central system is engineered to match the volumetric demands of the target facility layout. System configurations are determined by total pipe run calculations, simultaneous operator usage coefficients, and the bulk density of the materials being transferred.

• Multi-Stage Centrifugal Blowers (Hoffman & Lamson) — Utilizing premier Gardner Denver Hoffman & Lamson centrifugal exhausters for high-capacity, large-scale central vacuum systems. These units deliver a variable volume performance curve that automatically scales energy consumption relative to the number of operators currently utilizing the system, ensuring steady static pressure and exceptional operational efficiency.
• Regenerative Vacuum Producers — Compact, low-noise, and low-maintenance regenerative vacuum units engineered for smaller facility footprints, localized tool attachments, or dedicated single-process extraction lines requiring continuous high-vacuum performance.
• Positive Displacement (PD) Blower Packages — Heavy-duty rotary lobe vacuum pumps designed for ultra-high-vacuum applications involving long horizontal conveying distances, steep vertical drops, and dense bulk material cleanups.

Advanced Filtration Separators & Receivers

Legends filter receivers utilize advanced air-filtration technology to isolate fine suspended particles from the vacuum airstream, protecting the exhauster mechanisms while offering zero-emission plant discharge environments.

• Pulse-Jet Cartridge & Bag Filters — Automated reverse-pulse compressed air cleaning arrays that sequentially blast filter elements internally while the system is fully operational. This continuously sheds dust cakes from the media surfaces, maintaining a steady differential pressure baseline.
• Confined Space Entry Elimination — Filter receiver housings engineered with large side-access walk-in plenums or top-loading quick-release doors. This intentional structural design enables operators to execute rapid, toolless filter element inspections and replacements entirely from the exterior of the vessel, completely eliminating the regulatory liabilities and safety hazards of confined space entries.
• High-Efficiency HEPA Secondary Safety Filters — Absolute secondary HEPA filtration modules achieving a minimum efficiency rating of 99.97% down to 0.3 microns, allowing the scrubbed vacuum exhaust air to be safely recirculated directly back into the facility interior to conserve building thermal energy.

Safety Principle & Combustible Dust Management

With industrial plant safety serving as the guiding principle across all system layouts, Legends Equipment designs and manufactures all central and portable systems in strict accordance with OSHA regulations, NFPA standards (including NFPA 652 and NFPA 654), and international ATEX environmental classifications.

• Explosion Venting & Flameless Deflagration Vents — Filter housings outfitted with certified, burst-calibrated explosion panels or flameless venting modules designed to safely relieve high-pressure thermal energy away from workers and structural walls during a combustible dust deflagration event.
• Chemical & Mechanical Isolation Systems — Fast-acting mechanical isolation valves (flap valves) and chemical suppression arrays positioned on the primary inlet ductwork to prevent an explosion flame front from propagating backwards through the piping network into the main production facility.
• 100% Grounded and Bonded Components — Complete static-dissipative material transfer pathways utilizing specialized conductive hoses, carbon-fiber tools, and compression couplings outfitted with heavy-duty copper grounding strips to completely prevent the accumulation of electrostatic charges and spark discharge hazards.

Heavy-Duty Portable Vacuums & Overhead Cleaning Tools

• Explosion-Proof Portable Units — Certified Class I, Div 1/2 (Gas/Vapor) and Class II, Div 1/2 (Combustible Dust) portable industrial vacuums utilizing specialized air-operated venturi systems or explosion-proof electric motors to ensure safe point-of-use cleanups in volatile areas.
• Ergonomic Carbon Fiber Cleaning Tools — Rigid, ultra-lightweight carbon fiber extension wands and specialized cleaning attachments that enable a single worker to easily clean overhead roof trusses, light fixtures, and high vertical walls up to 30 feet from the safety of the plant floor, eliminating the need for scissors lifts, scaffolding, or fall-protection rigging.
• Color-Coded Anti-Cross-Contamination Accessories — Food-grade, chemical-resistant hoses and cleaning utensils available in vibrant, standardized color patterns (Blue, Red, Yellow, Green) to assist facilities in maintaining strict allergen isolation, chemical segregation, and cross-contamination prevention guidelines.

Industries Served

• Grain, Agriculture & Milling — Management of highly combustible grain dusts, corn starch, flour, and animal feed ingredients across large elevators, processing plants, and packaging structures.
• Chemical Processing & Plastics — Source capture of toxic chemical powders, fine carbon black, synthetic resins, polymer pellets, and fine abrasive additives during blending and conveying cycles.
• Pharmaceutical & Nutraceuticals — High-containment cleanup of active pharmaceutical ingredients (APIs), excipients, vitamin powders, and tablet press residues requiring secondary HEPA filtration and washdown sanitation.
