Rotary Screw Compressor Spares Manufacturer and Exporter
Hiraba Engineers is a rotary screw compressor spares manufacturer and exporter, producing reliable replacement and compatible spare parts for leading compressor brands including Atlas Copco, Chicago Pneumatic, Kaeser, Ingersoll Rand, KG Khosla, ELGi, and Kirloskar compressors. Because we manufacture in-house rather than buy in and resell, every part is built and tested to the same standard before it ships — helping customers get efficient performance and reduced downtime, whether they're buying one unit or placing a bulk export order.
Oil Separator
An Oil Separator, also called an Air-Oil Separator, is a core component in rotary screw and rotary vane air compressors. Its job is to separate oil from compressed air before the air exits the system — which is what keeps output clean, protects efficiency, and prevents oil carryover from creeping up over time. Hiraba Engineers manufactures oil separators for consistent performance across duty cycles and exports them to distributors and plant teams who need dependable supply, not a one-time order.
Air Compressor Filters
An Air Filter protects the quality of compressed air at the source. Its main function is removing dust, dirt, and other contaminants from intake air before it reaches the compressor, which protects internal components from premature wear and keeps performance efficient. As a manufacturer, we control filtration ratings batch to batch, so customers aren’t left guessing whether this shipment performs like the last one.
Oil Filter
An Oil Filter keeps the compressor’s lubrication circuit clean by trapping contaminants before they reach moving parts. A clean oil supply means better lubrication, less internal wear, and a longer working life for the compressor’s rotor assembly. Hiraba Engineers manufactures oil filters engineered for a precise fit and consistent flow rate, reducing the risk of oil starvation or premature component wear.
Valves & Control Components
Valves and control components regulate how air moves through the compressor and keep pressure within safe, efficient limits. A single faulty valve can throw off an entire system's performance, which is why Hiraba Engineers manufactures each of these to precise sealing and response tolerances:
- Inlet Valve / Intake Valve — controls the volume of air entering the air end, directly affecting compressor loading and unloading.
- Unloader Valve — releases pressure during start-up or idle periods so the motor isn't working against full load.
- Safety Valve / Pressure Relief Valve — releases excess pressure automatically to protect the system from overpressure damage.
- Solenoid Valve — electrically controls air or oil flow as part of the compressor's automated control sequence.
- Non-Return Valve (NRV) / Check Valve — prevents compressed air from flowing backward into the compressor when it stops or unloads.
- Drain Valve (Manual / Auto Drain Valve) — removes condensate and moisture that collects in the system, protecting downstream components from corrosion.
- Minimum Pressure Valve (MPV) — maintains a minimum system pressure so lubrication and separation continue working correctly at low loads.
- Pressure Regulating Valve — holds output pressure within a set range regardless of demand fluctuations.
We manufacture and export these as individual replacement parts as well as part of larger valve kits, depending on what a customer’s maintenance schedule calls for.
Lubrication System
The lubrication system keeps the rotor assembly running smoothly, manages heat, and directly affects how long the compressor lasts between overhauls. Hiraba Engineers manufactures and exports the following lubrication system components:
Compressor Oil / Lubricant
formulated for thermal stability and extended drain intervals under continuous screw compressor duty.
Getting the lubrication system right isn’t optional on a screw compressor — poor oil quality or a failed cooler is one of the fastest ways to damage a rotor assembly, so we manufacture these components to hold up under real operating conditions, not just lab tests.
Service Kit
A Service Kit bundles the components a compressor needs for routine maintenance — typically an air filter, oil filter, oil separator, and lubricant — matched to a specific make and model. Rather than sourcing four separate parts for a scheduled service, plant teams can order one kit and know everything fits together. Hiraba Engineers manufactures and exports service kits built around real maintenance schedules, not generic part bundles.
