The man accused of tipping hydrochloric acid into a lubricant dispenser at a Sydney gay sex club has appeared in court.

Hengky Irawan, 62, tried to hide behind a yellow envelope as he emerged from Parramatta Local Court on Tuesday morning.

Police allege Mr Irawan entered the suburban Aarows sex club on Bridge St at Rydalmere, in Sydney's north-west, a month ago and attempted to pour the acid into the dispensers.

However, police said the dispensers were alarmed and he was caught by security guards at the 24-hour 'discreet gay, bi and swingers club'.

The Mortdale man's lawyer asked the court for a six-week adjournment so he could undergo a psychiatric assessment for a mental health application.

He has been charged with administering poisons with intent to cause pain, entering a licensed premises to commit an indictable offence and intentionally or recklessly damaging the dispenser.

Police allege he drove to the Bridge St property on a suspended driver's licence at 10pm on August 27. He has also been charged with driving on a suspended licence.

He then allegedly entered the multi-storey club, which has a sauna, a spa and room to work out, charge sheets show.

Investigators allege he tried to administer the acid in the dispenser about an hour and 40 minutes later, at 11.48pm, and damaged the device in the process.

In a desperate bid to stop himself being recognised, after court on Monday Mr Irawan fled down the streets of the city and darted into stores.

He appeared at court alone, in a white dress shirt and dark pants and declined to comment.

The matter returns to court November 1.
