Maintenance Technician (Monday - Friday, 8:00AM to 4:30PM

At National Trade Supply, the Maintenance Technician III is a senior‑level technical role responsible for keeping our air and water filtration manufacturing facility running safely, efficiently, and without interruption. This position works across the full breadth of facility systems — electrical, mechanical, pneumatic, hydraulic, and fabrication — and is expected to diagnose and resolve complex equipment and facility issues that others cannot.

Responsibility for this role extends beyond production machinery to include the physical facility itself: building systems, infrastructure, utilities, and the overall condition of the environment our team works in every day.

This is a hands‑on role for a skilled tradesperson who takes pride in precision, is highly motivated, responds with urgency to downtime, and brings the technical depth to handle both planned preventive maintenance and unplanned breakdowns. The Maintenance Technician III serves as a resource for less experienced team members and is expected to lead by example in both safety and craftsmanship.

• Troubleshoot, repair, and maintain electrical systems including motors, motor controls, drives (VFDs), PLCs, sensors, and wiring up to 480V.
• Read and interpret electrical schematics, wiring diagrams, and ladder logic to diagnose faults.
• Install, modify, and commission electrical panels, control circuits, and instrumentation.
• Maintain facility lighting systems including replacing fixtures, ballasts, and bulbs throughout the building; coordinate lighting upgrades or repairs in production, warehouse, and common areas.
• Ensure all electrical work complies with NEC standards, NFPA 70E, and company safety protocols.

• Perform preventive and corrective maintenance on production machinery including conveyors, laminating equipment, cutting machines, and assembly line equipment used in air and water filtration manufacturing.
• Diagnose and repair mechanical failures including bearings, gearboxes, belts, chains, couplings, and drive systems.
• Perform precision alignment of shafts, pulleys, and couplings using appropriate tools and techniques.
• Read and interpret mechanical drawings, equipment manuals, and technical specifications.

• Troubleshoot, repair, and maintain pneumatic systems including compressors, air lines, regulators, solenoid valves, cylinders, and actuators throughout the facility.
• Read and interpret pneumatic schematics and diagrams to identify component failures and system inefficiencies.
• Replace and calibrate pneumatic components to restore proper system pressure, flow, and function.

• Inspect, maintain, and repair hydraulic systems including pumps, cylinders, valves, hoses, fittings, and reservoirs on production and facility equipment.
• Identify and resolve hydraulic leaks, pressure issues, and system failures using schematics and diagnostic tools.
• Perform fluid analysis, filter changes, and system flushes as part of a scheduled preventive maintenance program.

• Design and fabricate replacement parts, brackets, guards, and fixtures using welding equipment (MIG/TIG/stick) and other shop tools.
• Read and work from mechanical drawings, blueprints, and sketches to produce parts to specification.
• Select appropriate materials and fabrication methods to ensure durability, safety, and cost efficiency.

• Serve as the primary point of contact for all facility‑related maintenance issues, ensuring building systems and infrastructure are maintained in safe, functional, and professional condition at all times.
• Perform and coordinate repairs to building systems including HVAC units, exhaust fans, rooftop equipment, and ventilation systems; elevate to outside contractors when scope exceeds in‑house capability.
• Maintain facility plumbing systems including sinks, drains, toilets, water lines, and water heaters; identify and resolve leaks, blockages, and pressure issues promptly.
• Inspect, maintain, and repair facility doors, dock doors, dock levelers, roll‑up doors, and entry hardware; coordinate preventive maintenance on dock equipment to ensure reliable daily operation.
• Maintain interior and exterior…
