Step 1: Initial Setup and Installation

Given the unit’s weight of nearly 1,200 pounds, you will need a forklift or a pallet jack to move it into its final position. Ensure you have a flat, level concrete floor. The unit requires a dedicated 460V 3-phase power supply, so a qualified electrician is necessary for the hardwiring. You will also need to connect your compressed air piping to the outlet. Because it includes a built-in dryer, you do not need to install a separate dryer unit, which simplifies the entire process immensely.

Step 2: First-Time User Guide

Before powering on, check the oil level in the sight glass. The unit is shipped with oil, but you should confirm it is at the proper level. Once power is applied, the PLC touch screen will light up. The initial setup involves setting the target pressure (typically 125 PSI) and adjusting the timer for the auto-drain function on the dryer. The interface is surprisingly intuitive, with clear icons and a logical menu structure. It will prompt you through the first start-up sequence.

Step 3: Core Functions and Daily Use

Once running, the compressor operates completely automatically. The PLC controls the start and stop cycles based on demand. The rotary screw design means it runs smoothly and continuously. Your main daily task is to check the PLC screen for any warning lights or maintenance alerts. It will tell you exactly when to change the oil, filter, and separator element. For applications like painting or sandblasting, the integrated dryer ensures you are getting clean, dry air directly from the 20hp air compressor with built in dryer.

Step 4: Advanced Techniques

Experienced users can dive into the PLC settings to customize the system. You can adjust the load/unload setpoints for more precise pressure control. There is also a night-setback mode that can reduce pressure and save energy during off-hours. Learning to read the maintenance log on the PLC is a pro-tip that will significantly extend the life of your machine.

Step 5: Maintenance and Care

The core maintenance routine for the best 20hp rotary screw air compressor involves three main items: the oil filter, the air filter, and the oil separator. The PLC will track hours and alert you. You should also drain the moisture from the air receiver tank manually once a week as a backup to the auto-drain, and check the oil separator element every 500 hours. Keeping the cooler fins clean is also essential for optimal performance.

Step 6: Troubleshooting Common Issues

If the unit fails to start, check the emergency stop button and the main power disconnect. If you see a “High Temperature” alarm, it usually means the cooling fan is blocked or the ambient temperature is too high. The PLC display provides error codes, and a quick look at the manual will tell you the exact issue. For complex electrical problems, contact Trollastor support directly.

Expert Tips for Maximum Value

Tip #1: Optimize Your Piping System

Use a looped piping system with ball valves at drop points to maximize air pressure and minimize condensation. We recommend using high-quality quick-connect fittings for each drop.

Tip #2: Schedule Oil Changes Religiously

Use the PLC alerts to change the oil and filter exactly on schedule. This is the number one way to extend the life of your rotary screw unit.

Tip #3: Keep Cooler Fins Clean

Dust and dirt build-up on the oil cooler is a common cause of high-temperature shutdowns. Use compressed air to blow out the fins every month.

Tip #4: Install a Secondary Filtration System

For critical applications like medical air or powder coating, add a high-efficiency particulate filter after the integrated dryer for ultimate air purity.

Tip #5: Use an Auto-Drain Valve

While the unit has an auto-drain, you can install a timer-based solenoid valve on the tank bottom for even more reliable moisture removal during periods of non-use.

Tip #6: Monitor Inlet Air Temperature

Try to install the compressor in a cool, well-ventilated area. Every 10-degree reduction in intake air temperature can improve efficiency by about 1%.

Common Mistakes to Avoid

Mistake: Ignoring the PLC Maintenance Alerts. → Solution: Never reset an alarm without investigating the cause. The alerts are your first line of defense against major repairs.
Mistake: Using Improper Lubricant. → Solution: Always use the manufacturer-specified synthetic oil for rotary screw compressors. Standard compressor oil will cause rapid wear.
Mistake: Blocking Airflow. → Solution: The compressor needs at least 3 feet of clearance on all sides for proper cooling. Do not box it in.
