A Kings Lynn-based filtration and environmental technology group has made a good start to the year with turnover up 9% in the first four months.
Porvair, which has its headquarters on the North Lynn Industrial Estate, said profits were in line with expectations and order books were healthy.
The company specialises in the laboratory, aerospace and industrial sectors and has made several bolt-on acquisitions over the past two years.
In December it acquired Dutch robotics firm Rohasys BV which it said would had been performing as expected and attracting interest from the laboratory division's customers.
Porvair added it had completed a deal for American firm Keystone Filter, which makes filter cartridges for the food and beverage and chemical processing markets in the US, in February. Plans to move the operation to its Virginia plant were said to be on track.
