20HP Fixed-Speed Single-Stage Screw Air Compressor

System Architecture & Core Functionality

The 20HP Fixed-Speed Single-Stage Screw Air Compressor is an integrated rotary solution designed to deliver a continuous, non-pulsating flow of compressed air. This specific power class is optimized for modular industrial setups, providing a stable 2.4-2.8 m°/min (at 8 bar) discharge to drive critical automation, precise pneumatic actuators, and demanding manufacturing tools.

Technical Specifications (Performance Parameters)

Strategic Engineering Advantages

Low-Speed High-Torque Air End: Unlike many suppliers, we use a larger air end frame running at lower speeds (under 3000 RPM) to minimize heat generation and friction-induced energy loss.

Independent Oil-Cooling System: Features a specialized thermostatic valve that maintains oil temperature above the dew point to prevent condensation and internal rust.

High-Stability Electric Control: The unit is equipped with a heavy-duty PLC cabinet featuring Phase Sequence Protection and Motor Overload Protection to handle unstable power grids.

Simplified Maintenance Layout: All consumable parts (oil filter, air filter, separator) are positioned for 15-minute rapid replacement.

Operational Reliability & QC (Direct from Factory)

As a dedicated China factory, we focus on "Site-Readiness." Every 20HP Fixed-Speed Single-Stage Screw Air Compressor undergoes:

Noise Level Audit: Ensuring the cabinet’s sound-dampening foam meets the < 68 dB(A) industrial standard.

Pressure Drop Test: Verifying that internal pressure loss across filters is < 0.02.MPa.

Oil-Carryover Analysis: Confirming clean air output via high-precision separator elements.

Why Choose Seize Air 20HP Unit?

Global Logistics & Protection

We utilize a "Reinforced Export Package" strategy. Each unit is bolted to a steel-reinforced base and enclosed in a multi-layered plywood case to withstand sea-freight humidity and multi-port handling.

Engineering FAQ

Q1: How does the "Fixed-Speed" logic handle the motor's starting current (Inrush Current)?

A: To protect your factory's electrical grid, our 20HP Fixed-Speed Single-Stage Screw Air Compressor utilizes a Star-Delta (Y-Δ) starter. This reduces the starting current to approximately 1/3 of the direct-on-line value, ensuring a smooth ramp-up and protecting the motor windings.

Q2: What is the benefit of the "Single-Stage" design for 20HP applications?

A: At the 20HP power level, a single-stage compression ratio is highly efficient for pressures up to 13bar. It offers a simpler mechanical structure with fewer moving parts than two-stage units, significantly reducing maintenance complexity and initial CAPEX for the owner.

Q3: Does your factory provide OEM/ODM customization for specific color or branding?

A: As a professional China manufacturer, we offer full customization of the sheet metal housing, color (RAL codes), and PLC interface languages to align with your local market branding requirements.

Q4: What are the critical maintenance intervals for this model?

A: We recommend the first oil and filter change at 500 hours (break-in period), and every 2,000 to 3,000 hours thereafter, depending on the site’s dust levels. The high-capacity air end is designed for an overhaul interval of >50,000 hours.
